> Touchscreen gestures are trivial to implement You have never worked at the raw level of getting a touch screen controller (especially the older ones, todays once are much nicer) working. The work Apple did to get first generation capacitive touch screens working is impressive, I say this with no more experience than having had to get later generation cap touch solutions working. The amount of clean up you have to do on the signal, the sheer garbage you get through, and then to figure out what gestures actually work reliably? I won't comment of if it is patentable or not, but it sure as hell is not trivial. Getting cap touch working involves close collaboration between the EE, ME, Firmware, Software, and UX teams. The nice little world of touch points software developers get access to at the highest layer is supported by a massive effort beneath.
