Re: Stability of future Ubuntu phones?
Ubuntu on phones won't have to support a hundred thousand hardware combinations; it'll really be optimized for whatever device it is preinstalled on. That should certainly aid stability.
Instability would turn a lot of people away from Ubuntu. It's given Motorola's phones a reputation they'll probably never recover from; too many people burnt by Motoblur.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
