Yeah, I'm sorry to say that is a result of good marketing. I work at a university and we have experience with a good number of XPS laptops.
We saw at least a 60% problem rate, and Dell's support was dog slow. Batteries being the weak spot. Because it's thin it is more fragile, we saw a number of broken screens, and keyboards. One survived a Gatorade spill, but another failed after a water spill. Go figure
A three year warranty helped, but we were out of a laptop for months at a time, more than once on the same laptop.
When you have battery life beyond 5s next year you'll be thankful
