Google is building its own DeX: First look at Android's Desktop Mode

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.

A laptop wins everytime because I don't have to carry around all my peripherals and set em all up again. Unless there's going to be dock setups in every conference room, coffee shop, table in my house, airplane, car, deck, etc, a laptop makes more sense.

The peripherals need not be anything more than a clamshell screen + keyboard, same as a laptop.

Right but if it's the same as a laptop why not just use a laptop?

The only things I can think of are you really want to keep all the data on your phone and don't want to use cloud sync solutions (Dropbox etc.), or you really want to save a couple of hundred dollars getting a (probably terrible) laptop without a motherboard. Not very compelling IMO.
