I actually tried the Vita the other day when I was in best buy. And by tried I mean I went up put my hands on it and determined the buttons were too small for me to consider buying. (Barring an extremely compelling line up which would probably require years to accrue)

It is funny how hard Sony worked cramming all that technology into such a package, and it took me all of two seconds to determine I don't want one based on the shape of the buttons.
