I have an iPad2 and as far as gaming is concerned (so, not web browsing and the like which obviously benefit from the bigger screen) I often wish I had an iPhone instead. Pretty much every game with virtual d-pads, buttons, sticks, etc, I feel should be better on a smaller and lighter device, not to mention the majority of them having the controls at the very bottom on iPad which means they're always uncomfortable and that even for many of those that they can be adjusted to be more near the middle height your fingers may then be hiding too much of the action, ie, stay right on top of where enemies and obstacles first appear as you scroll by. I also think I'd enjoy games like Rage HD more on iPhone, the iPad is a bit heavy and unwieldy to move around. But I suppose full point & click adventures are nicer to view on iPad. And games with less than Rage's motion control but still few virtual inputs, like Real Racing 2, although I don't imagine that being worse on iPhone either. I guess, the grass is always greener etc.
