I had a bad experience with a XPS 9550 that I bought a few years ago. But the XPS line probably evolved a lot since then, and my particular model was defective.
It hasn't. I got a top end Precision 5550 from work. It is derived from the same platform I think. It cost £3100. Problems:
1. When you pick it up the touchpad clicks
2. The screen has built in vignette like a 1930s camera.
3. It sounds like a Concorde taking off.
4. It overheats at least twice a day, triggers a "CPU thermal event" and goes into hibernate
5. If I plug it into the dell dock it crashes one in every 3-4 times completely hosing what you're doing.
6. The keyboard is like typing on stepping stones from Takeshi's Castle.
7. They keyboard has all the wrong keys the wrong places.
8. It has three USB-C holes and only one of them still works.
9. When it arrived the packaging was so badly designed it was almost impossible to get it out of the plastic crate that was nestling inside the large lump of cardboard designed by someone fresh out of university in China.
10. It overheats after exactly 3 minutes every time you switch the Nvidia RTX on.
11. The battery lasts about 2 hours if you're lucky.
12. Sometimes when you shut it down or hibernate it doesn't actually shut down and turns the battery contents into heat over the following hour or so leaving you with a brick when you get it out later.
13. It takes twice as long to compute anything CPU intensive as my ass end M1 MBA which doesn't suffer any of those problems and cost less than 1/3 of that.
It's garbage. I hate it. On a positive note they ordered me a 16" MBP after complaining for the last month.
I would be seriously pissed if I'd paid for it out of my own pocket.
The worst time to buy any windows computer is right upon us. I've been using windows on and off professionally since about 1992 and it's just absolutely horrible soul crushing waste of my life and money at this point. I want nothing to do with the platform any longer. I haven't even written up a rant about windows itself yet.
The only killer niche in the PC space at this point is providing mid to high end desktop workstations which are too damn expensive from Apple.
