Summary: Sony's decision to use this proprietary memory is embarrassing. The Vita could have been successful using USB memory. But no... they handicapped the device out the gate with this ridiculously priced buffoonery.
Summary: So I have a PS Vita and I have three memory cards (4 GB, 16 GB, and 32 GB). I bought a 32 GB memory card and thought that would be the end of me buying memory cards but I was wrong. 32 GB is a lot of memory, but if you plan on buying a ton of content (ie...games, movies) from the Playstation Store then you'll need more that one 32 GB card. The 32 GB memory card I bought is almost full and I need to expand by buying another 32 GB memory card.
