Oh sorry I didn't mean double the price for double the battery. I just meant paying extra, since price point seems to be a huge deal at the moment considering the 3DS had a major cut recently. Other than that I don't know about physical battery sizes and all that.

I'm of similar opinion with Lionx that I don't really need my games on the go, and that's just my lifestyle. That and I guess being a non-FPS player is limiting what I'll like on the system. Once more unique games come out in the genres I'm interested in, then I'll be a bit more serious in my consideration for the Vita, just like with the 3DS.
