Man, I tried this too but eventually went back to a laptop. Though maybe that wouldn't have been the case if I was able to use chroot. Still, for me, a laptop is quite nice for being able to just whip it out and start doing stuff immediately. With phone + glasses + external keyboard, I have to pull out several things and plug in the glasses.
But proot being slightly too slow is a real bummer. I was able to get a lot of stuff working natively on Termux, but every once in awhile you hit a wall and it's sad.
proot is just good enough to make you want to try it, but not good enough to keep using it. chroot was far better and if that's what was holding you back I'd recommending trying chroot.
I can relate to the clunk of having 3 different pieces to the setup, but I found myself using just the phone + keyboard pretty often for quick things. And since the desktop environment seems to sit in the background just fine, it wasn't much more than just turning on the phone and opening the keyboard. So in that sense it wasn't much different than a laptop.
