It's been a while since I've bought a laptop with a usable trackpad. For example I just got a Dell, a $1,500 Studio 15 not a crappy low-end one, and the trackpad is broken. I've even had it replaced but it still refuses to move the cursor about 50% of the time. Mice are preferable to every trackpad I've used, even Apple ones.

Of course this doesn't address things trackpads can do that mice can't, like multitouch gestures. But for pointing quickly and accurately, I always have a mouse paired to my laptop.
