This singlehandedly proves, this has nothing to do with patents, hardware, or anyhting
Motorola just felt like it.
I have used the webtop "mouse" and have no idea what you're referring to.
No one is arguing that the hardware is limited to 2 points. The touch driver has a hardcoded limit. You can verify this by either using one of the multitouch test apps (Dotty, etc) or by coding your own and debug incoming touch events (MotionEvent.getPointerCount() will never exceed 2).
This means there was an arbitrary reason why Motorola did this. What reason could this be...
Performance? Yeah, 10 touches never brought the Galaxy S to a crawl, and the Atrix has beefier specs. Unlikely reason.
Incompatibility with MotoBlur? Possible but unlikely- code that supports 1 or 2 touches will simply ignore events with pointer IDs beyond 1 or 2.
Not useful? Unlikely- there are plenty of games and apps that support more than 2 touches. Personally, I find the lack of more than 2 points frustrating when using a SNES emulator.
Besides the Apple multitouch patent feud, what other reasons are there for Motorola to cripple a flagship device?
