harder perhaps, but not impossible, and the market has had decades to figure this out.

My guess is typical PC manufacturers have not felt it worth the time to invest in getting this aspect right.

Ironically, the best non windows trackpad I ever used was when Vizio tried to make computers. They actually got the trackpad right. In fact, those computers were really cut above everyone else, but my guess is they didn't sell well because they were taken off the market almost as fast as they were introduced
