I was really looking forward to this, then they announced the prices of the memory sticks and all that jazz and I lost my interest. If you go for the 3G, that's 300$, then say you choose the biggest memory stick(since you don't want to run out of saving power right off the bat), you then get two games and your pushing 500$ for a portable console, and while it's nice that it's emulating a PS3, I'm trying to see why I'd choose this over a PS3... outside of portability, the PS3 is better, better graphics(slightly), built in memory, hooks up to your TV, it's cheaper, has a larger library and in the long run I find that console games just don't feel right for handhelds, as they seem more better played when you're at home, sitting in a chair, rather then on the move. Really, all the Vita gives me over the PS3 I own is touch screen and six axis, which my 3DS already has.
I just couldn't justify the price, so I decided to spend my money on spoiling my Wii.
I'll probably get a Vita in 2-3 years, when the price levels out and the memory sticks aren't stupidly priced.
