My Dell Precision 7750 touchpad works flawlessly and I'm running Ubuntu. The touchpad is optimal size, similar to that of Apple's I think. It also has 3 physical buttons, middle click is my favorite which by default is configured to open a link in a new tab. Multipoint touch and gestures work fine as well, at least those that I use - two finger touch for right click menu and two finger gesture for scrolling. Because it's a rather new touchpad by Dell, Initially the physical right button didn't work, which was a bit annoying, but eventually the problem was solved with kernel update.
