For some ungodly reason, I haven't seen any windows laptop with a nice trackpad that doesn't break in 6 months :(. At least my Acer netbooks have reliable trackpads (no gestures or anything, but ...)
I nave a Dell laptop and it has a great trackpad. Gestures work consistently, I use them all the time. The only real annoyance is that the material of the trackpad is not the most comfortable for finger swiping but it's alright.
