I am VERY sure that the Tab is the only reason why there'll even be an iPad v2 this quickly with cameras and all. Until Apple gets honest-to-God competition, they tended to be happy with lazy progress. (i.e. 1st gen vs 2nd gen iPhones, iTouch, iPods, etc. back when there wasn't very good competition).
They're maemo and MeeGo... "Meamo!" sounds like what Zorro would say to catherine zeta jones... after she slaps him for looking at her dirtily...
