resistive screens can support multi touch.

the only real difference from resistive and capacitive, is that capacitive does not require to be slightly PRESSED to register, but rather, touched.

capacitive is better for 'dull' touches (finger, sausage), resistive is better for exact touches (stylus)

resistve = 2 layers of clear stuff. when touched, they press against eachother, registering a touch.

capacitive = the whole screen is a capacitor, when you touch it, a change is registered in the voltage, where that change happens registers as a touch.
