@nman: The multitouch trackpad on the new macbooks and macbook pros is amazing. You seriously have to use it to understand. It's also more comfortable on my wrist than using a mouse. I'm not a gamer but gaming obviously requires a mouse so if you're a gamer then forget it.

@nman: I prefer the trackpad on my laptop than any mouse. It's a preference thing. For me the trackpad works.

@nman: Because "crappy" trackpads don't require any lifting, are very accurate, take the least space, don't need a particular surface, do kinetic scrolling (and other useful gestures) and they're consistent with what you use on a laptop.
