As a counterpoint to that (and maybe it has just been a particular model series), I've had the 9343 XPS13 for 5 years now without issue. The battery life is much shorter now, for sure, but it's been a daily driver for all that time so I'm not so surprised.
I don't recall the model number anymore, but I also had an XPS13 for around three years at my last job. Had it running linux as my primary machine for web (and some mobile) development, and the only issue I ever had was that the onboard microphone sounded pretty bad.
I've seen a lot of bad reports, so maybe I just got lucky, but I hope not since I loved that machine and the XPS line would be pretty high up on my list if I was in the market for a new laptop now.
I'll just add on to this. Also have had an XPS13 as a daily driver for about a year and have nothing major to complain about. A slight coil buzz while charging, nostril cam and shitty microphone are some minor gripes, but all in all it's been great.
