- The touchpad is just garbage compared to the MBP, to the point I have an even more keyboard centric setup on it than my desktop, because I want to drop it out of a window every time I use the touchpad.
- Fans. I've accepted that most laptops will run active cooling more than any radiative chassis MBP, but the issues are that while the fans run constantly, they also change speeds constantly in both Windows and Ubuntu. They'd be far less annoying if they ran at a higher, but steady RPM by averaging response over a large time window. Manually managing fans feels like 1998. Also, for a $3.5K laptop that runs fans constantly, these are some of the jankiest, most rattling prone fans I've heard. Most colleagues with XPS 13/15 have sent them in for fan replacement at least once.
A more niche gripe is that 16:9 is the wrong aspect ratio for a professional laptop.
Pros:
- Screen quality and brightness.
- Keyboard (why I can't just get a new MBP).
- Hardware configurability.
- Many hardware issues at first, especially in linux, were quickly and effectively fixed by Dell driver and firmware updates.
