By the time I hit publish on this review, something interesting had happened: Dell revealed that its XPS 15 laptop was outselling the smaller XPS 13. How could that be? Most flagship notebooks these days have 13-inch displays or smaller. And for good reason: Ultraportables are, by definition, thin and light, delivering longer and longer battery life with each passing year. But, as they say, different strokes for different folks. There are indeed people out there who need more - more horsepower and more screen real estate - even if it comes with the slight inconvenience of a heavier design. For those folks(and Dell says there are lots of them), the XPS 15 should mostly fit the bill. Just don’t stray too far from a power outlet.
