I keep forgetting to check it. I tried to get a video from Videos Unlimited, though, and it wouldn't accept my Sony Rewards card info. It downloaded videos fine during that $30 credit for new users.
I've had my tablet for a few months now, havent seen an update on anything and the ps store is pretty week. I've heard that sony services are combining, would be cool to be able to put ps minis purchased on ps3 to the tablet!
