I haven't found any non-Apple laptop with a trackpad that's even close. Everything I've tried on the Windows/Linux side has been bad enough to be a deal-breaker.
(imo of course) OS X beats Linux for keyboard shortcuts because they are more consistent. My ranking is: 1. OS X, 2. Linux, 3. Windows.
I'm a keyboard junkie, to a fault sometimes, but I find that I use the trackpad on my MacBook quite a bit because it's so useful with all the gestures and such.
Hmm, I guess you're right. Without the dedicated context menu key, you have to use SHIFT+F10. That's a pain.
