Don't forget the no gaemz.
No but seriously, the PSP had a much larger variety of games, the fact that it was also a multimedia device helped but what really drove it was the huge library of games (GTA, MGS, Mega Man, Castlevania, countless RPGs, etc). The Vita is missing many of the games which pushed the PSP, and at least in North America and Europe it's why it's not doing so well.
