Are they though? Phones already have a broad range of uses. I've seen people try to make laptops out of them and it just doesn't make sense for a number of reasons:
- As screen size goes up so do battery requirements, so you're already paying for a screen, a chassis, and a physical keyboard. Why not go the whole way and pay for the silicon?
- When your phone is being a PC it's no longer being a phone; you can't do phone calls and camera photos (at least not well) while it's a PC.
I have a Samsung and use Dex occasionally, but the uses are limited. In my case it's to check personal emails, which is not allowed on the corporate network. But outside of cases like this I can't imagine ever preferring Dex to a laptop or a dedicated computer. It's much better at being a phone.
I'm a developer so I have my needs which are unlikely to be "completely fulfilled" by a Phone-as-computer either.
However "as screen size goes up so does battery requirements", my thought was to keep the device docked in a Dex dock with PD and a fan for cooling, and since the resolution on modern phones is so damn crazy, as long as the device screen isn't pumping pixels when connected it should be fine to do 2k.
While it's a PC it's docked so you can't take calls on the phone easily (unless you have a long cable) but you could with a headset. Now I am not talking about the Dex implementation, I'm in the "what can be" discussion for the future.
For "normal people" a good Android desktop would be a lot better than not having a "desktop setup" at all. They don't have to buy a new device but can still get a mouse/keyboard/display combo and so some "productivity tasks".
I tried Dex out on a S10 or something but it wasn't enough for me other than as a cool gimmick, but I definitely see a usecase that could become widespread.
I travel a lot and do not like carrying things, so xreal and phone are more than enough for coding while going day long, easily augmented with a small power bank (unlike a laptop), with all of that fitting in my pockets after I drop my luggage at the hotel. Most my colleagues have macbooks and while they have good battery life, it is no comparison: the search for places with power outlets starts when I am not even at 50%. It is not an apples to apples as I do a lot of compute in the cloud, but even with that on the laptops, they still last a lot shorter and you cannot plug in normal power banks.
The silicon only has to be fancy, because phones are so constraint in terms of space, power and cooling.
Getting phone-like performance in a desktop or laptop form factor and power and cooling budget is a lot simpler and cheaper.
> They don't have to buy a new device but can still get a mouse/keyboard/display combo and so some "productivity tasks".
The point was that they do have to buy a new device. The only thing they don't have to buy is new silicon. But that's trivial compared to everything else.
