I did think of that, although Apple didn't do a great job advertising that the single-button MacBooks could do right-clicking with a trackpad gesture. For the people in the PC world, that was a complete unknown. My previous notebooks had scrolling ability, tap, and double tap, but the trackpad never did anything like right-clicking.
If those rumors are right, I still think that's quite a horrible idea. Sometimes Apple really doesn't understand "if it ain't broke, don't fix it." (Shrunken wireless keyboard, glossy-only iMacs, anyone?)
