And for quicly typing on a screen keyboard with 2 fingers, multi-touch is mandatory, as well as for gaming. Devices with no keyboard or d-pad need multi-touch. This is the reality. Not true at all. The Nokia 5800 is Nokia's best-selling smartphone right now, it's selling on a similar scale to the iPhone and it has a plain old resistive touchscreen with single touch and no keypad. You might like multitouch and it might be useful in some situations but it is not mandatory. If it was mandatory why are so many non-keyboard non-multitouch touchscreen phones selling so well?
