Agreed Apple touchpads have the best feel and responsiveness.

You can always buy a Magic Trackpad - they connect via Bluetooth so they are not too inconvenient.

Wacom pen & touch pads are almost as good. I use one when I'm running Gimp - it's great to have different responses to the pen and to touch.

I have yet to find a notebook which is even close to Apple's touchpad quality.
