I played Super Meat Boy on PC, and i have to say that it's absolutely awesome.

But i think it would be much better if it can be available for handhelds, too. So here's an analysis:
- It cannot be for Android or iOS due to uncomfortable controls (excluding the 99 cents iOS game).
- PSP/ PSVITA and 3DS have comfortable controls, but 3D on 3DS is a must, so for starting SMB on handhelds it can be on PSP/ VITA and later put on the 3DS.

I played this game with a PS2 controller (with an USB adaptor) and it's very comfortable (Circle for jumping, R1 for running). Even that control scheme can be easily put on the PSP/ VITA.
Also, the PSP/ VITA need addictive games and also 2d platforming games.

The problem with the PSP is that it has a lot of games that require much time to play and enjoy. Also, that explains the Angry Birds' success, a lot of fun in short bursts of time. Super Meat Boy also has that achievement, but handheld gaming needs it!.
