Picked my Vita up form the shelf today to play a bit while my wife watched some show of hers and on a while pulled the phone out to compare size. Screen size is nearly identical (.2" difference). Remembered the Vita has a relatively low resolution so I decided to google spec differences... virtually none. The phone has a slightly better CPU, the Vita has a slightly better graphics card.
There are few games for the Vita I actually like as an RPGer. I have Vita Persona and Disgaea, but the 2 8gig Vita cards i have are filled with PS1 and PSP games (Thanks to TN and Uno).
With 96gigs available on my phone without swapping cards (32gig built in plus a 64gig card) and PS1 and PSP emulators available for android, not to mention 4g net, higher screen resolution, and easily available crazy battery life... it seems that my phone is actually a better gaming platform than my Vita. That's terribly, terribly sad.
It seems that until Vita has some more RPG action from this generation it's going to stay shelved...
