I got a Dell XPS 13 last year and the touchpad is great. I use it both on Windows and Ubuntu.
I also remember having a Toshiba something-or-other 10 years ago and hating the touchpad in comparison to a Mac. So, just saying, I've seen how bad it can be. The XPS has given me no issues aside from having to make sure I change the click behavior (tap to click really annoys me).
Does tap-to-click really get in the way if you turn it on but don't want to use it? Are you 'tapping' as your finger comes down onto the trackpad to move? That action should be detected and ignored, IMO. I'm only saying this as a tap-to-click user. I can't stand using someone's keyboard if they've turned it off — there I am, tapping away, looking like an idiot ...
