I have a Dell XPS13 Developer Edition. I like it but the trackpad is the weak point for me. An external mouse is not the solution to that.

I haven't wanted to use a mouse since 2006. I much prefer the trackpad on my 2014 MBP to any mouse. For me it's worth it for the gestures alone.

Each to their own I guess.

Edit: The good news is that the trackpad support is improving constantly especially with Wayland.
