My XPS 13's trackpad works quite well Fedora 34 Gnome. Firefox supports smooth scrolling and pinch-to-zoom like in Windows or Mac OS, and Gnome Shell has built-in trackpad gestures for switching workspaces and showing all open windows.

That's the thing which keeps me from buying a new notebook. :( Everything else I care about is on par with intel macbooks but the touchpad is too important.

Trackpoint works well! (it's the "fingertip joystick" in the middle of the keyboard)

There will be haptic trackpads out this year. This one doesn't have it.
