I’ve been using a Dell XPS-15 9560 for over six years now, the keyboard needed to be cleaned after four years and and the charging port needed to be replaced (€10 inc service) recently. The battery no longer lasts 11 or so hours but it lasts 2 or so which I’ll take, for about €100 I could replace just the battery.
All of which, for how fast devices tend to break on me, is an incredibly good mileage I’d say!
And oh yeah, whatever Linux I’ve been distro hopping to has worked swimmingly!
