When the new XPS 15 review arrived at my home, I thought there was a mistake. The box just didn’t seem big enough to hold a 15-inch laptop, or at least not one the size of last year’s model. And while I wasn’t quite right about getting the wrong device, I had good reason for being a bit confused. Despite sporting a familiar design, the new XPS 15 9570 is an entirely different beast. And if Dell’s goal for the XPS 15’s first revamp in four years was to retain the best qualities of the XPS line while improving its performance, portability, and overall usability, I think Dell nailed it.
