Multi-Touch from a pure TECHNICAL standpoint is actually not at all the same as a touch screen.
This is nothign about "use two fingers to turn an image" crap.. this is a TECHNOLOGY patent about the TECH of our the multi-touch works. A normal touch screen back in the day was pressure sensetive, or at least could not distinguish multiple fingers. Apples tech actually is a system to distinguish any number of touches on a device. THIS is what they patented, and I do not think anyone else had it before.. if anyone did, then the patent is invalid or is moved to the company that did it before, thats how patents work...
