I'll stick with physical so I can know 15 years from now if my vita breaks and I need to replace it I will still be able to play my games because whether sony still supports the vita via PSN won't matter.
plus that way I can lend out games like persona 4 to my friends to get them hooked with out having to hand them my whole system. I've never found the step of swapping out a physical copy all that troubling. That being said though PS+ is doing a great job of getting me to get digital goods, things that outside of the PC and rock band DLC I rarely ever spend money on.
As i have said before though, memory card price aside, given the push for digital sales on the vita, it's a sad joke that the vita doesn't have on board room for games.
if digital got me lots of savings I would be more tempted to use it. In general in the US going digital on anything but PC costs us more.
because I don't really have any interest in on-line shooters (I'm old and my eyes are bad and my reflexes suck); basically, unless there's a substantial single player mode, the game has no appeal to me, so I had no idea that the game that was going to "save the Vita in the West" had been received so horribly.
