I used it primarily as a great ssh terminal, better than any Android app I used so far (but ConnectBot is good). I worked on a Rails and on a Node app on there, fixed a server for a customer when in a hotel on the other side of the world.
I'd rather reverse the setup. Linux first with phone calls and SMSes, an Android emulator or whatever for the apps that nobody will ever develop for Linux (banking OTPs, etc.) But I don't feel optimistic. I think that the only reasonable chance is that today's hardware (which is good enough even for mid level phones) will get so cheap and firmware so available (FOSS or supported) that somebody will use it to make a decently sized and light phone with Linux.
