This is a solved problem, isn't it? On my Dell M6800 with Ubuntu 16.04, the touchpad experience is very poor, I avoid using it. On my (Linux based after all) Chromebook Pixel (anno 2013) it's fine, never been tempted to connect a mouse. Perhaps I should clarify: the difference is also a difference in usage: on the Chromebook I use the trackpad almost exclusively to select the current window or scroll its content, rarely set the cursor or highlight some text to be copied (the latter is already more challenging than with a mouse, I'd say). I haven't attempted to use a CAD program using the touch pad yet. So the touchpad works mostly fine for what a Chromebook is useful for, it's no replacement for a mouse on a workstation.
