A big part of it might be the latency. I'm on an Asus ultrabook (UX430) with a pretty wide, smooth clickable touchpad, but I still don't use it much because it has a noticeable latency that makes it very frustrating to use compared to that of a Macbook. I've noticed the same problem on many laptops (Lenovo ideapad for instance, while my old Thinkpad x220's trackpad was responsive and so more usable despite being absolutely tiny).
