android 3.0 is bound to be buggy, and for me that isnt much of a dealbreaker when you look at the value of this thing.
Granted the annoyances you are facing would be enough for anyone to return the unit, for me i love being able to face issues and have them solved/fixed through my blood,sweat and tears (well actually lots of energy drinks and late nights LOL)
the potential of this unrefined(software wise) machine is so high(even without tegra3) that it gives me wet dreams. (im so horny to try out ubuntu on it) Once honeycomb is in full developement swing and the apps come rolling in and google sends out the upcoming updates i'm sure that this tablet will shine.
In any case its up to you what you decide to do with your machine but on the offchance you do go back to ME and return it LMK so i can get the open box deal :P
enjoy it while you have it.
