PSP is in a bad light with companies, eh?
Anyway, I carry my Eee everywhere, and it's not like she can't last for about 3-4 hours when playing a game or anything. Not as portable as a cell phone or a PSP, but still... pretty useful, and I can connect to the internet whenever I feel like.
That aside, I feel current multi-touch/tilt games feel... gimmick in a weird way. I mean... not like it's that hard to think of a way to use multi-touch, right? Like... a game like DMC, where you use one finger to guide your character and the other to execute attacks like... you slash left, you slash right... etc... Or a racing game where you use one finger to turn your car, and the other to strafe it... Or a game like Mirror's Edge where you have two analog nubs on the bottom right and left corners of the screen to navigate and to execute any action, you just need to tap the screen in designated coordinates.
Those are just for multi-touch. Obviously with the tilt sensor, there can be much more fun. They just haven't paid that much attention.
Oh, and having Flash on the iPhone might or might not be able to remedy this problem... well... depending on whether Adobe would support multi-touch and tilt, either via natural classes or via fscommands... I'll take a look at it if it's ever out, and maybe I'll buy an iPhone just so I can experiment with that.
