Will Windows laptops ever have a good trackpad?

I use a Dell at work and a Macbook Air at home and the trackpad on my Macbook Air sweeps the floor with the Dell. My wife's HP laptop is also mediocre and very frustrating to use. Why is the trackpad performance on Windows machines puke inducing? Will they ever get reliable multi-touch and two finger scrolling to work more than 3/4ths of the time?
