You know what would be a VERY nice feature? A Video-Out port to plug the bloody thing into a TV so you don't go cross-eyed trying to see the tiny screens.
My two-cents...
The only problem I see with that idea is that the bottom screen is all touchy-like.
well, if they worked it out so that the main game screen was on the TV, but keep the touchpad screen working as well...dunno how that'd affect other games though...I only have FF3 and 4 for mine, and you don't even need the stylus...
