I love my Vita.
I play it almost everyday.
With the vast amount of free titles that ps+ dishes out every month for the Vita, there is never a shortage of Vita titles to play.
Compile that with the ability of remote play, my Vita gets much play.
Fact to the matter is, the Vita has a far better line up than the Wii U does.
More Original Vita games, more Indie titles, Remote play with PS4 games. No wonder the Vita is selling better.
