Is this the ultimate 15.6in Windows laptop? Laptop design has evolved beautifully over the course of the past decade. Compare a 2016 machine with one from 2006 and you'll typically find it to be thinner, lighter, faster and far more attractive to look at.

But the push for a sexier profile isn't always a good thing. Thinner, smaller laptops aren't quite as productive, performance can be sacrificed, and you often tend to lose out on something rather important, be it all-day battery life, a well-stocked array of I/O ports or something as simple as an optical drive.

Dell reckons it can overcome some of those challenges and combine the sleek design of a modern machine with the performance and usability you'd expect from something larger. Enter the XPS 15.
