Stand aside Apple, Dell's just built the best ultraportable laptop. More than three years ago I wrote about Intel's $300 million investment plan to develop Ultrabooks. Lightweight long-lasting well-specced PC laptops to offer something approximating the MacBook Air experience, just not made by Apple.

It took PC vendors a long time to shape up, and there are still rough spots to the whole PC laptop experience?the proliferation of models and options remains more complex and confusing than it should be, for example?but with the 2015 edition of the Dell XPS 13, it's fair to say that PC vendors have not just matched the MacBook Air experience, they've beaten it.
