What horrible prices. I am glad I got a few cards cheap a few months ago. Picked up about 3 4GB ones at Best Buy for $7, got a 16GB from Gamestop for $20, and got a 32 GB one at Best Buy for $45. I do not even own a Vita. I am waiting for the third model to come out. The second has a terrible screen and the first is inferior to the second save for the screen, so I will wait for the third model.
... Kmart is selling the 4gb cards for like a buck fiddy. I own a Vita and won't even bother buying those. They are utterly useless. I have a 16gb card that I got cheap, used once, and never used it again.
Switching cards in the Vita is such a painfully long process. It just makes the pain of trying to use multiple smaller cards actually worse than biting the bullet and taking out a second mortgage for a single good size card.
