+1 to this. You currently have a lot of devs switching to the Dell XPS 13/15 (myself included) from the MacBook Pro line, wanting to give Ubuntu a go and speccing that particular laptop out with it.

Coming from mac, the most jarring experience of moving over is the trackpad. We know that for most trackpads, you can configure them to have similar behaviour for clicking (two finger right click, one finger click, no dedicated buttons), but it is hidden in config files etc. The option to emulate this experience should be baked into Ubuntu and made easy to access.

Palm rejection is also another big point with these trackpads. It doesn't work very well out of the box.

And we know that the hardware is more than capable enough since the XPS touchpads conform to Microsoft's "precision trackpad" spec.

I can't emphasize how annoying bad palm rejection is. I can't have my cursor randomly jumping across the screen and selecting windows that I don't want to type into (always seems to be at the worst time).

Try libinput. I configured my XPS 15 with libinput and it's been a blessing in disguise.
