I owned a PSP but i didn't use it much ( I was a lot younger and there weren't many games available) but it seems there will be good games coming out soon on the ps vita
Update: I have an iphone and a laptop too so i would basically only use it for gaming ( no music, nor pics, nor browsing)
Update 2: i also have a ps3
