>One thing I've seen across all the vista installations I've seen or dealt with is rock solid stability - moreso than XP. Users generally either like Vista or hate it (I'm moving to the hat it side), but it is solid as a rock on compatible hardware.

Well, that's the thing. The lawsuit is about the Vista Capable certification. It appears M$ lowered the bar to help Intel and the users buying what should have been compatible hardware were just forgotten about in the quest for profits.
