Off topic, but how is this experience using the Surface Pro X as a PWA machine? Does Windows / PWAs work well in tablet form? I was thinking of switching to a similar setup and using it essentially as you describe. Seems like it could be a really lightweight and simple computing environment similar to Chromebooks but still allows you to run traditional Windows apps as well if you need.
I really like it but I wish Microsoft would support FOSS developers better and provide more support and incentive for them to port more developer tools. There are almost no native aarch64 programming languages for Windows 10. If you keep yourself inside WSL then you're good to go because Linux under aarch64 is quite complete. On the windows side of things you'll probably running a lot of 32bits x86 apps.
Which is one of the reasons I like PWAs, they are ISA independent and are working pretty well here. Unfortunately Firefox doesn't support an add to homescreen feature on the desktop, so I used Edge to do it for the apps I want to have a nice icon for (such as spotify).
If you're going to use it much like a chromebook then it might be a tad too expensive to be justifiable. I don't regret buying mine at all, I really like it, but I'm sure they'll release cheaper ARM64 Surfaces soon, I'm betting on a Surface Go with ARM64 at some point.
