I bought a 2015 DELL XPS 13 (9343) Developer Edition with Ubuntu. Ubuntu 16.04 has worked very poorly on it from the start. The installer crashed and I had to reinstall. Then the wifi was very slow. It would frequently lock up on resume. Hardware video decoding would occasionally crash and switch to software decoding which is choppy and eats battery power. The touchpad registered clicks while typing. One time the wifi suddenly stopped working after an update. Each of these problems was mostly solved by spending a few hours researching and running various commands as root. Some were fixed by updates after a few weeks. The latest bug is that right-clicking on the taskbar (panel? dash?) does not show any popup menu. So the only way to add buttons for launching programs is to make text files on the desktop with a special format.
I'm sick of the bugs in my Linux laptop. I'm about to get a Mac again.
