Err... if you look at the goal of MeeGo, it's not going be ran on any specific hardware definition. Windows 7 Mobile Series (I find that a odd name) and the iPhone both dictate the hardware used for the OS. In Apple's case, they make the hardware and OS. In Microsoft's case they've laid out rules for what hardware the device must have to run the OS.

Meego on the other hand is like Android, it can be put on nearly any device with any configuration of hardware. Thus just because the next Nokia device may have a capacitative multi-touch screen doesn't mean another MeeGo device will. Thus any developer that says writes only software that uses multi-touch will find their market limited, than if they wrote software that could use multi-touch and say a resistive input also. Or a keyboard control scheme.

But that's the issue Android is having right now anyway.
