Try Ebay if you haven't. Got my Vita with a game and some memory for a very nice price.
It's definitely not a bad system, but (no matter what people say) I think it still has a pretty under-developed library. There's definitely titles worth buying...
if you're into those titles.
But yeah. Sony's attempts at making sure their handhelds/games aren't hacked, edited, etc. have only ever hindered their sales, and I don't know WHY they can't see that. The memory is priced in a ridiculous fashion. Same for the PSP (at the time, at least)... plus, the whole UMD thing.
And it's a shame. I actually like my PSP and Vita better than my DS and 3DS, in general, and I won't be very happy if Nintendo ends up having a monopoly on the mobile gaming part of the industry (well, minus tablets and such, but I'm talking dedicated handheld gaming platforms). I don't really care for 1st party Nintendo titles, so that'd really put a bee in my bonnet, especially considering that I do more handheld gaming than console gaming. :/
