The comparison to TV remote is wrong: better: why do we need a TV remote that you can only use with gloves made of anti-static conductive foam and where you have to press two buttons at once to get one action.
Sorry but I never needed Multitouch up to now. In my opinion a user interface that needs two fingers instead of one is somewhat broken.
It seems that resistive touchscreen can do multitouch: http://en.wikipedia.org/wiki/Resistive_touchscreen I for myself do not see the need for it. Why I rather like resistive touchscreen: "Resistive touchscreen technology works well with almost any stylus-like object. In some circumstances, this is more desirable than a capacitive touchscreen, which has to be operated with a capacitive pointer, such as a bare finger." and "Capacitive sensors detect anything which is conductive or having dielectric properties. ... A standard stylus cannot be used for capacitive sensing, unless it is tipped with some form of conductive material, such as anti-static conductive foam. Capacitive touchscreens are more expensive to manufacture and offer a lesser degree of accuracy than resistive touchscreens.[5] Capacitive touchscreens cannot be used with gloves, and can fail to sense correctly with even the smallest amounts of water - you could use a resistive screen briefly in the rain, or with wet hands, not so with a capacitive screen. ..." http://en.wikipedia.org/wiki/Capacitive_sensing I think this is a huge disadvantage for capacitive touchscreens as I always want the choice between stylus, my finger and a glove (if it is cold outside). Needing an additional property ("having dielectric properties") is senseless for such devices.
