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

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.

I don't see that at all.

That's because I think over time the processing power of a eg laptop will become a small fraction of its costs (both in terms of buying and in terms of power).

The laptop form factor is pretty good for having a portable keyboard, pointing device and biggish screen together. Outsourcing the compute to a phone still leaves you with the need for keyboard, pointing device and screen. You only save on the processor, which is going to be a smaller and smaller part.

Even in your scenario, most of your devices will be idle most of the time anyway. And they don't use any energy when turned off. So you are only saving the cost to acquire the processor itself.

Desktop computer processors that can hit the computing power of a mobile processor are really, really cheap already today.

Having all your data always with you stored locally (on your phone) is simpler than syncing and more private than cloud.

One OS with all your software. No need to install same app multiple times on different devices. Don't need to deal with questions like, for how many devices is my license valid for. However, apps would need to come with a reactive UI. No more separate mobile and desktop versions.

Example, you take a photos on your phone, dock it at your desk or laptop shell, and edit them comfortably on a big screen, with an app you bought and installed once. No internet connection is required.

A docking station could be more than just display and input devices. It could contain storage for backing up your data from the phone. Or powerful CPU and GPU for extended compute power (you would still use OS and apps/games on your phone with computations being delegated to more powerful HW).

This could replicate many things cloud offers today (excluding collaboration). No need to deal with an online account for your personal stuff. IMO, it would probably be less mystical than cloud to most users.

You need to sync it anyway. Having that phone with you all day also means exposing it to a lot of risk involving theft, drops and other kind of damage. You need that sync for backup purposes.

I agree actually having it on the phone is great though. I use DeX a LOT, it's a great way of working when I don't have my laptop with me but do have a docking station available (e.g. at the office when I forget my laptop or just dropped in unplanned)
