Talk about extremes, the Sony Ericsson Xperia X10 only supports single-touch input (at least for the time being), but its gaming successor, the Xperia Play (Playstation Phone) will support up to 32 simultaneous touch inputs. The Xperia Play uses a Cypress TrueTouch-digitizer (CY8CTMAxxx) according to the guys at TBGUS in their recent teardown. This may seem extreme considering the amount of digits you could realistically fit on a 4.2-inch screen, but it’s a nice dilemma to have coming from the X10.
