Pretty cool, even though I deleted my Twitter months ago and never regretted it. Kind of like Myspace, or any other social app. Unfortunately though I still have a Facebook, it is somewhat of a valuable resource for things... like stalking.
I don't get the twitter reference, never used the thing or really looked at it. But that touch wall is pretty sweet. Reminds me of minority report just less awesome. That program to translate signs was really cool. Would be handy for world travel if it works that well.
