A phone that docks as a desktop Ubuntu would be perfect for my use case. I use desktop computer (Mac Mini) in three locations, and I have bought spare keyboards, dual monitors and mice for all of these. My phone is already more powerful than the desktop. But even when I had a laptop, I never used it on the move - always plugging into docks with monitors and full-size keyboards. It would be very convenient to have a single computer to set up and carry with me in a pocket, instead of having to either sync work and settings via "the cloud" all the time, or carry a backpack for the mini.
