Why is it so hard for Microsoft to get the touchpad right ?

From the review:

It’s much better than before, but it’s still too small and frustrating in the way trackpads often are on Windows machines. I’m constantly mis-clicking or mis-dragging things and never know whether I should be blaming Windows, the hardware, or my fumbling fingers.

It is hard to believe that Microsoft finds it hard to replicate the touchpad of a Macbook Pro in any of its own devices. It is something that Apple managed to get right almost 8 years ago, this should have been a non issue for Microsoft by now.

Are there any legitimate reasons, like patents, holding back Microsoft?
