Which handheld should I get? 3ds vs dsi vs psp

[Vindibudd]

I was looking into getting a new handheld console. and I have it narrowed to these three. Anyone have a preference or good reason why I should get one or the other. The dsi is at a very sweet price point at $99 now while I have a PS3 and the PSP would work well with the classic psOne games. The ads is just the latest nintendo handheld and will have netflix streaming soon. Any thoughts?

If you're older then 15, you want the vita.

lol well, I don't want to drop $250 on the vita plus another $30 for a memory stick. At least the 3DS has a 2gig sd card included.

Which will be great for playing such captivating titles as Pokemon and Mario brothers.
