Acer Aspire S3. Asus Zenbook UX31. Lenovo IdeaPad U300S. Toshiba Portege Z835. HP Folio 13. And now, Dell's XPS. Since Intel and its OEM partners set out to beat the Apple MacBook Air on price and match its exceptionally thin, superbly solid build, six Windows laptops have risen to the challenge... and while a few have come close, none have quite done the job. The XPS 13 is Dell's entry into the ultrabook arena, and while it's got the same basic specs as most of the other thin-and-lights we've recently reviewed, it might be the most comfortable ultrabook we've ever held. Not only did Dell fit a 13-inch panel into a smaller chassis than any of its competitors, but vast expanses of soft-touch plastic paint make its keyboard deck feel great, and the entire base of the laptop consists of a stylish carbon fiber weave. Starting at $999, the XPS 13 looks fantastic at first blush.

Does that feeling permeate the entire laptop experience, though? Read on.
