There's a reason we've heaped praise on Dell's XPS notebooks over the past few years. They've always been gorgeous and capable machines, with near bezel-less screens that other computer makers quickly copied. Most importantly, they brought an air of refinement to the Windows laptop market -- something you could previously only find from Apple. Dell's latest XPS 13 continues that tradition of excellence, though there are some changes that might irk longtime fans of the lineup.
