I'm not a huge fan of touchscreens, but my wife considers them an essential feature. Would hate to see them phased out completely, as it does provide consumers with another feature to opt for (I kind of look at touch screen vs. standard keypad navigation as being like Qwerty vs. SureType-choice is a good thing).
Along with the iPhone, HTC still does touchscreen on some of it's handsets (MDA, Wing).
