My experience with Linux drivers has always been dicey... do they also have lots of issues running Windows? Heat and throttling problems are, in my experience, endemic to Macbooks too.
Purchased one about a year ago. Screen, sound card, and keyboard needed to be replaced on arrival. Replaced the screen and sound card under warranty and sold it disclosing that the keyboard’s spacebar sometimes inserted two spaces on one press. Have Dell’s QA issues on this laptop gotten any better?
Coming from a Mac, stuff that just works there is a constant struggle on the Dell XPS 13. It is pretty though.
