I tried it for a while with the best AR glasses I could find at the time, XReal Air 2 Pros with an Xreal Beam, and although I could see the potential, it wasn't good enough to get work done. The screen size was too small, the resolution too poor, and it was a little too jittery and unnatural feeling.
Are the Xreal One's that much of a step forward that you can use it for serious work? Even on my Quest Pro I find it just on the edge of being too annoying to do coding-work. Web browsing is decent.
And second question, worth buying the One or waiting for the One Pros?

Taking better advantage of a display is nice but imo the really exciting part of desktop mode is the planned integration with Google's Linux Terminal app (i.e. 1st party linux VM support). I have a Samsung DeX device and while you can get a basic dev environment working easily it can be really cumbersome to make it comfortable to use and integrate with your normal tablet workflow. Being able to install full-fat linux apps and run them in a window would be a complete game changer.

Dex is annoyingly close to being really useful.
I think Samsung recently added a "desktop Dex" mode that's supposed to be less mobile-ui. I haven't tried it tho.
asabla
I remember when they presented the S10, with the initial implementation of Dex.
It felt so close already back then, sluggish, but still usable. But that initial implementation was running some in-house version of Ubuntu with a custom kernel (if I remembered it correctly).
I just wish this becomes a reality much sooner then later. Especially if I can have my dev environment on some remote VPS with either tunneling, github code spaces or Azure DevBox

Just FYI, Dex is really fluid on flagship devices.

Rumor is Samsung won't support Google's Linux Terminal (at least for their existing phones) since their Knox conflicts with the Android Virtualization Framework :-(.
Honestly I'd like to see Windows 11 running under this as well, but that seems incredibly unlikely.

this done well is a transformational thing, its just no one has been willing to invest yet, but the compute on a phone is now good enough to do most things most users do on desktop.
I can easily see the future of personal computing being a mobile device with peripherals that use its compute and cloud for anything serious. be that airpods, glasses, watches, or just hooking that device up to a larger screen.
theres not a great reason for an individual to own processing power in a desktop, laptop, phone, and glasses when most are idle while using the others.

> the compute on a phone is now good enough to do most things most users do on desktop.
Really, the compute on a phone has been good enough for at least a decade now once we got USB C. We're still largely doing on our phones and laptops the same things we were doing in 2005. I'm surprised it took this long
I'm happy this is becoming a real thing. I hope they'll also allow the phone's screen to be used like a trackpad. It wouldn't be ideal, but there's no reason the touchscreen can't be a fully featured input device.
I'm fully agreed with you on the wasted processing power-- I think we'll eventually head toward a model of having one computing device with a number of thin clients which are locally connected.
dzdt
The future of personal computing is being dictated by the economics of it, which are that the optimal route to extract value from consumers is to have walled-garden software systems gated by per-month subscription access and/or massive forced advertising. This leads to everything being in the cloud and only fairly thin clients running on user hardware. That gives the most control to the system owners and the least control to the user.
Given that all the compute and all the data is on the cloud, there is little point in making ways for users to do clever interconnect things with their local devices.
mushufasa
in a sense apple is already doing this, since there's shared chip tech in the laptops and phones.
I still will prefer the form factor of a laptop for anything serious though; screen, speakers, keyboard.
Yes you can get peripherals for a phone, yes I have tried that, no they're not good. Though perhaps with foldable screens this could change in the future.
danieldk
Apple is intentionally hampering the desktop experience on the iPad and is very late in brining Stage Manager to the iPhone (the rumor is now iOS 19). Until there is serious competition (this and/or improvements to DeX, Apple will drag their feet because they want to sell you three compute device categories (or four if you count the Vision Pro).
logic_node
True! Apple’s already ahead with the shared chip setup between Macs and iPhones. But yeah, for real work, nothing beats a proper laptop — big screen, keyboard, good speakers. I’ve tried using a phone with accessories too… not the same vibe. Maybe foldables will change that someday!

I think we've seen this before. Back before phones were "smart" there was one (Nokia, maybe?) that you could put on a little dock into which you could plug a keyboard and monitor.
Obviously, it didn't take off. Perhaps it was ahead of its time. Or, as you say, it wasn't done well at the time.
Phones accepting Bluetooth keyboard connections was very common back in my road warrior (digital nomad) days, but the screen was always the annoyance factor. Writing e-mails on my SonyEricsson on a boat on the South China Sea felt like "the future!"
Slightly related, I built most of my first startup with a Palm Pilot Ⅲ and an attached keyboard. Again, though, a larger screen would have been a game changer.

Still in the "smart" era, but the Motorola Atrix allowed that.

I remember there was a fad I think in 2009 or 2010 where a bunch of Android manufacturers released 'laptops' (just a display and keyboard) with a dock connector in the back that was meant to turn the phone into a laptop basically
Obviously the trend didn't take off

There have been multiple attempts at this over the years.

AIUI, the main problem in the cell phone era is that by the time you create a notebook shell with an even halfway-decent screen, keyboard, battery, and the other things you'd want in your shell, it's hard to sell it next to the thing right next to it that is all that, but they also stuck a cheap computer in it (and is therefore no longer a dock). Yeah, it's $50 more expensive, but it looks way more than $50 more useful.
What may shift the balance is that slowly but surely USB-C docks are becoming more common, on their own terms, not related to cell phones. At some point we may pass a critical threshold where there's enough of them that selling a phone that can just natively use any USB-C dock you've got lying around becomes a sufficient distinguishing feature that people start looking for it. Even just treating it as a bonus would be a start.
I've got two docks in my house now; one a big powerful one to run the work-provided laptop in a more remote-work-friendly form factor, and fairly cheap one to turn my Steam deck into a halfway-decent Switch competitor (though "halfway-decent" and no more; it's definitely more finicky). We really ought to be getting to the point that a cell phone with a docked monitor, keyboard, & mouse for dorm room usage (replacing the desktop, TV, and if whoever pulls this off plays their cards right, the gaming console(s)) should start looking appealing to college students pretty soon here. The docks themselves are rapidly commoditizing if they aren't there already.
Once it becomes a feature that we increasingly start to just expect on our phones, then maybe the "notebook-like" case for a cell phone starts to look more appealing as an accessory. We've pretty much demonstrated it can't carry itself as its own product.
That would probably start the clock on the "notebook" as its own distinct product, though it would take years for them to finally be turned into nothing but shells for cell phones + a high-end, expensive performance-focused line that is itself more-or-less the replacement for desktops, which would themselves only be necessary for high-end graphics or places where you need tons and tons of storage and you don't want 10 USB-C drives flopping around separately.
nasretdinov
BTW you don't even need a dock if you have a USB-C monitor with USB and audio ports, which is not that uncommon. The monitor acts like a USB hub, so if you plug in your keyboard and mouse that's your computer essentially
carlhjerpe
This is the only natural path if mobile chips are going to keep getting faster, everyone with a flagship phone is "wasting" so much good compute resources that never gets utilized.
I wonder if we'll see USB-C docks for phones with fans blowing at the device for improved thermals.
If they nail the Linux container UX as well as ChromeOS it would motivate me to buy a top-tier device rather than my sluggish Fairphone 4, right now I don't see the usecase other than good camera.
Imagine thst a large userbase could just skip the laptop and desktop in favor of a USB-C dock and a decent display :)
saratogacx
The original Samsung DeX dock for the S8 was exactly that. USB-C and had a fan in the stand to keep the phone cool.
https://www.digitaltrends.com/mobile/samsung-dex-first-impre...
xnx
I've tried it. I was pretty impressed. I plugged in a USB-C hub with a keyboard, mouse, and monitor and everything worked immediately, even the Windows key on the keyboard.

Android has supported basic peripherals and screen mirroring for a decade at least, and several vendors have tried to bring plug-in phones to the market as desktop alternatives. The fact people still find out about this feature today shows how badly the feature was marketed. Samsung Dex is good enough for 90% of office work these days, if not more. For a short time you could even run fully-fledged Ubuntu through DeX, which would've made the phone a full desktop replacement.
I wish there was a phone-laptop-dock solution that wasn't as expensive as an equivalent Chromebook. My phone is more than powerful enough to act as a travel laptop, yet its potential is constrained by a small touch screen..
stanac
I always thought that MS will make something like that. Android phone with "business" app store and docking support for external screen and peripherals. IIRC one of the last windows phones was from HP with dock support. I guess after the windows phone they just gave up.... There was an attempt at making dual screen ms android phone which was a failure (at least from business perspective).
packetlost
I mean, what I really want is chromebook shaped shell that I slot my phone into for travel with an extended external battery.
simpaticoder
This is very good news. Especially in light of recent attention given to the possibility of CPU shortages. Lots of programming tasks can be done comfortably on a smartphone. For example, no build front end programming. The description "desktop view" is unfortunate since it calls to mind a browser mode where the site is displayed as it would be on a desktop. And this is something completely different. I do hope this mode does not require an external display because it would be quite useful even with the phone's native display. Especially given their hypixel density and the availability of reading glasses.
bee_rider
I’m not sure I follow on the cpu shortage front. Phone cpus by their nature are attached to a degrading-over-time battery, and are much more power constrained… I have an already 6 year old i7 in my desktop… it can keep up with modern software still in a “I don’t even think about it” manner, which is to say I cranks through anything other than a large numerical simulation (dang Intel, I would have needed to go to an i9 to get AVX-512 back then I think).
Anyway I could happily get a couple more years out of as a main PC, then it will probably have a few years in it as a hand-me-down or tv computer.
That said, I generally agree that, I mean, we’re going to get phones anyway so it is nice to get something useful out of them.
the_clarence
I switched from a lifetime of iPhones to an android phone last year, just because of folding phones. They are amazing and IMO the reason why Apple is going to have issues as these get cheaper (unless they release a folding phone too). Now that I have all this screen estate the current UI feels limiting often.
jccalhoun
Rumors are Apple will be inventing the folding phone in a year or two.
hbn
It's not like Apple hasn't had the ability to release a folding phone since the display technology has existed for years. The tricky part of releasing a folding phone is figuring out how you're going to handle the incredibly high warranty claim rate when screens spontaneously fail.
Apple in particular will get to deal with all the negative PR when people buy their $2000 iPhone Fold and online reports come flooding in for all of the week 1 display failures.
logic_node
Haha yeah, I’ve heard that too! Apple might be late to the foldable party, but you know how they do it — show up last and still steal the spotlight. If they really launch one, it’ll probably be super refined… and super pricey. Let’s see if they can change the game like they did with the notch!

How does this relates to the submission's "Desktop View"? Genuinely trying to find the connection.

The desktop view is for larger screens, it is somewhat similar to fordable phones.

I switched from iPhone to android a month ago and it was so awful that I just went back to using my old phone. I treat the android device as essentially a powerbank with a camera, and even that it's bad at. plug it into my PC to transfer pictures? no response
chneu
Smells like user error and bias.
I've swapped dozens of users from iOS to Android in the last year or so and nobody has had issues. Over the years I've helped hundreds of people migrate. Most everyone really likes the freedom to use different apps or workflows.
The only folks who ever have problems are people who need to be told how to use their devices. Choices confuse them so android is overwhelming, which is understandable. That's where iOS excels. iOS dictates how users can do things, which works for some people but also atrophies people's understanding of technology. People learn to do as they're told, not how to think about what's going on. Apple's walled garden makes people worse at technology.
Also sounds like you bought a garbage bargain android device. Idk how something can barely work as a camera/powerbank unless user error is present.
danieldk
I have been an iPhone user since 2009, but take 'Android-excursions' every few years. I am currently using a Pixel 9 and I can't see why it would be worse than an iPhone. Functionality-wise they are pretty much on-par. Sure, there are some differences, Pixels have much better AI functionality, iPhones better Mac integration. But I don't see a clear advantage of either, except that Android hardware is much more affordable (you can pick up a still pretty-ok Pixel 8a new for 379 Euro here currently) and Android has more customizability (but good out-of-the-box defaults).
And you have the bonus that with a Pixel you can remove big tech from the equation when needed with GrapheneOS.
That said, I would only recommend people to buy Pixel or Samsung A5x or up. They are the only Android phones that have reliable monthly updates [1], plus they are the only two brands that are not vague about having a truly separated secure enclave (Titan M2/Knox Vault respectively). Other vendors don't really talk about it and probably only use ARM TrustZone.
[1] Pixel is the only phone that gets them really on time, but with Samsung it's normally within a month on A5x and the flagships.

Is your PC a Mac? Apple doesn't support MTP because they want iPhones to look good or something. Every other OS with a reasonably complete Desktop Environment will allow mounting an Android device as what appears pretty much as a standard USB drive. It's part of why I prefer Android. Using an iPhone on Linux/BSD is just not worth the hassle.
joshuaissac
> mounting an Android device as what appears pretty much as a standard USB drive
AFAIK Google got rid of built-in support for this in Android Jelly Bean. Additional tricks are needed to make later versions of Android behave as a USB Mass Storage device. If it works for you out of the box, I suspect it may be specific to your Android distro.
rcMgD2BwE72F
Curious to know what phone you got. A Pixel 9 with GrapheneOS is so much better than any iOS devices from my experience. But since users you have more freedom on Android, this will depend on what you do with it (e.g me, I use Syncthing to locally sync all my files and photos with several devices -- no cloud / subscription needed).

Why would you want to plug in if you can sync them over Wi-Fi using Syncthing?

nashashmi
I have been waiting for this to go mainstream for nearly six years now.
The whole point of having USB C phones is to connect to desktop docks and get full featured computers. Instead we have muzzled devices.
I would love something that I can use and maybe even use an RDP on, to function as a full desktop computer.
But like all common sense improvements, some come just too late after the boat has sailed.

> Google Is Catching Up to Samsung DeX
Does anyone use DeX?
NBJack
Yes! Have been using it since my first pair of 'AR' glasses when I want to get work done anywhere without dragging my laptop (corp or personal). If I ever find a folding bluetooth keyboard that can "lock" to remain stable in my lap, I'll be particularly happy.
ewoodrich
I use what I call “pseudo DeX” on my Galaxy Tab S8+ constantly. It’s basically the entire DeX laptop like UI without the requirement to use an external monitor (there’s an actual name for it I can’t remember).
It’s what Stage Manager on iPads should have been: a regular, boring laptop mode to make multitasking on a large tablet screen usable without Apple unnecessarily trying to put their own unique spin on it.
longtimelistnr
Funny you mention stage manager, i remember the absolute online letdown/meltdown that happened when it didn't ship with the iPadOS version it was scheduled to. The other day i encountered the button for it and completely forgot it existed, but after launching it, I remembered how useless it is.
Zambyte
I used it fairly regularly with a device called NexDock, which is essentially just a laptop shell that acts as a screen, a keyboard, a track pad, and a battery for a USB-C connected device. I mostly used it for web browsing, chatting, and Termux (usually SSHing into another system, but not always).
Since I got my hands on a Daylight Computer, I have basically been doing the same thing but with a tablet Android environment instead of DeX. It's been nice, but I would love a nicer window manager when I have a keyboard and mouse connected.
szszrk
Of course. Yet it's still a fraction of userbase.
I chose Motorola for the same reason (they have their own variant of dex which works smooth).

Pretty sure Windows Phone did this over a decade ago. I mean, say what you want about Windows Phones, but yeah, this was a thing.
TowerTall
It was called "Continuum" and was introduced with Windows 10 Mobile. Worked pretty smoothly but it couldn't run win32 application only the new modern UWP apps. Introduced 6 Oct 2015 alongside the Nokia Lumia 950/950 XL. Discontinued when Windows 10 Mobile reached end of support in Dec 2019.

I'm not aware of any Windows Phone implementation like this that existed commercially. Can you point me to it?
The first modern thing like this that I can recall is the 2011 Android-based Motorola Atrix phone[1] that presented a DeX-like desktop (well before DeX!).
It used an Ubuntu-based desktop. It was really, really good, but never got traction.
ThrowawayB7
The HP Elite x3 had it: https://en.wikipedia.org/wiki/HP_Elite_x3 . The phone came with a docking cradle with desktop ports.
rcmjr
It did. I have the 950xl and the display dock. At the time, it was such an awesome feature that the world and how we work was not ready for yet. https://www.amazon.com/Microsoft-Display-Dock-Lumia-HD-500/d...

Freaking cool. I don't know how I missed/forgot this, having been so immersed in the Windows Phone world. Thanks!
I feel like this is something that could spur Windows/Windows Phone adoption in modern times.
lern_too_spel
Display connectors were a problem back then. Now you can just use USB C.
nashashmi
They did. The lumia had this feature. It also had a liquid cooling system. But the windows computer was quite limited. This was before they migrated to windows one core.
buzzerbetrayed
As someone who likely never would have bought a windows phone, I sure wish Microsoft would have stuck with it
voidUpdate
Multitasking on a phone? I know screens are getting bigger, but it seems like a bit much to me... I can understand this on a tablet, but having two windows that im interacting with at the same time on a phone would feel really cramped, unless its one of those fold phones that are 2 or 3 in 1
bgnn
This is for when you connect it to a large screen
alias_neo
You plug in a USB-C cable with DP-Alt mode (or whatever phones use) and you have a (4K) display of any size, keyboard and mouse (via the USB hub in the monitor), and webcam, speakers, whatever else that's connected to your monitor/hub/docking station.
The phone just becomes the processing power; essentially an ARM laptop with all of the peripherals external.
I currently using Pixel 9 Pro XL (512GiB) and I imagine it's got more compute power than my ageing 2019 XPS 13.
Conversely, I'm not entirely sure what the use-case is. It couldn't replace my work-laptop with a 20-core CPU and 64GiB of RAM and ARC GPU, running Ubuntu/Gnome that I can also connect to a couple of monitors, keyboard, mouse, speakers, webcam, and more with a single cable via a docking station; and if I was going to carry the peripherals needed to do this with my phone, when on the go, I'd just carry a laptop, like I do now.
Curious to hear what the use-case is for people with these desktop/phone crossovers. If it's to cover the use-case where I haven't brought a laptop with me, forgotten it, didn't bring it for weight or whatever; where am I supposed to find these peripherals to use?

A secure device. Pixel with graphene and this thing lets you keep all your classified eggs in one basket, but it is a really hard to pry open basket. At home you can do stuff on it with the same comfort as on PC, but you can always have it in pocket.
lern_too_spel
Even on a phone, I regularly split my screen vertically to research while writing without swiping back and forth between apps.
If you haven't tried it, especially if your workplace allows your phone to have access to some corporate data, DeX + a good pair of AR or just integrated display glasses feels like the future.
I run my S23 Ultra with a pair of XReal One's, and a folding Bluetooth keyboard (DeX let's you use your phone as a touchpad). It is really amazing in widescreen mode sitting in a coffee shop, reading through technical documents and answering work email. When I'm done, it can all fold up and fit in a (spacious) pair of cargo shorts.
I think Samsung has played the long game on DeX, with an eye towards their collaborative XR glasses with Google next year. As great as XReal has been, I am eager to see a "first-party" solution.
