The acceleration curve makes so much sense to me, for some reason it feels right. Whereas I hate using Windows or Linux because it doesn't have the same sort of curve.

The touch-pads are extremely nice though. I have used Mac's since 2001 beginning with an iBook and since then find it difficult to use a mousing surface on other manufacturers laptops. It just doesn't have the same smooth feel, there is more resistance or it doesn't correctly pick up on my motions, the surface Apple uses to cover their touch pads is something special and different.

The acceleration curve came directly from NeXT (traditional Mac OS had a more similar curve to Win/Linux). So my best guess is that Steve Jobs also likes this acceleration curve ;)
