Am I the only one who finds the Synaptics trackpads on many laptops are simply a nightmare in itself regardless of the operating system due to the physical design? Not all Synaptics trackpads are created equal, on some machines, the surface friction just doesn't feel correct, making the pointer acceleration difficult to control.
I know I was probably using it wrong and I should've spent an hour tweaking the parameters in the Synaptics Windows Driver, but I don't really know what's the best for me. Even worse, some Synaptics trackpads have cheap plastic that worn out after a year or so, creating an uneven friction, making the navigation a difficult experience. I know I could replace it, but making the touchpad as a consumable item is not a good design. Also, on many ultralight machines, the available space is simply too small to have an adequate space for plamrest.
Finally, as a matter of personal preference, I found clicking the button on the touchpad is never a good experience - the pad is clickable, but only on its edge, or you could touch-click, but you need to constantly lifting your finger. The touch gestures are confusing as well, to this day I never figured out any of the gesture I could use. The device driver really should come with an animated tutorial. The only feature I found was scrolling at the edge or double-finger scrolling, but it's only useful if you want to scroll a few lines, rolling the entire page is a tiresome experience (unlike the middle-button scrolling on a TrackPoint).
As a result, I only use the TrackPoint on Thinkpad laptops. Although the TrackPoint is not completely free from the pointer acceleration issue in general on Linux (although I never found it to be an issue for me), the overall usability is much better because it doesn't have the physical design issues.
