It's a ripoff and I think it's a big part of why the Vita isn't selling. Even if they cut prices in half, it would still be too much.
In a round about way, I'm saying it's always better to buy boxed Vita games. They tend to retail $5 cheaper online at launch but you'd have to download a lot to recoup the cost of the memory card.
This was the biggest kick to the stones. If you're going to charge me a ton for your stupid proprietary memory it better be quick. IIRC the PSPs memory stick was pretty quick compared to competition, but was also used in several other Sony devices (cameras, etc) so demand wasn't tied to a single friggin device.
