If anyone is on the fence about buying a PS Vita, my advice is to use that money on a Nintendo 3DS. Nobody I know is happy with their Vita, but I love my 3DS. It has enough great first and second party titles that it makes up for the lack of third party content, in my opinion anyway, and with back compatibility for the whole DS library you can't go wrong. Not trying to incite anything here, just tossing in my two cents.
I own both a PS Vita and 3DS and I have to agree with what you've said... But, the Vita is a fantastic console as well. It might not get much AAA support, but you have a ton of great indie and japanese games, as well as a various exclusives that really make it worthwhile to have the console. You can also buy PSP and PSOne classics which makes it all the better as well.
Also, if you're a trophy hunter like me, then you can't go wrong with the Vita. There's tons of games with good trophy lists that can be platinumed in a couple days if you put enough effort into them. And don't forget that the Vita is NOT region locked, which means that you can import games to your heart's content!
