If you like a trackpad, you have a Mac, for the same reason. I don't know if it's the hardware or the firmware, might be some of both, but no one else ships a laptop with an acceptable response curve.

I stick with the Apple ecosystem for a few reasons, but this is a big one. Even when I'm at the desktop with keyboard and trackball, I'll reach over to the laptop sometimes to pinch, or three-finger swipe, just because it's the easiest way to express my intention. The context switch from using the keyboard to using the mouse is a fairly complete one for me, which is to say I tend to spend long stretches doing one or the other. I don't place any value on staying on the home row while switching. I do place considerable value on proper pointer and scroll acceleration, reliable recognition of gestures, and input rejection when my palm or thumb happens to rest on the trackpad. Any non-Apple laptop trackpad I've tested completely fails one or all of these.
