There are more ultra-mobile professionals now than ever before, which is why OEMs are developing increasingly thin-and-light laptops that will appeal to those users. No one wants to add heft to their bag, regardless of whether they're going off on a 10-hour flight or a 10-minute commute to work, thus increasing the appeal of thin-and-light laptops. But the most mobile among us will only go as thin and light as our performance needs allow us to—if a laptop isn't powerful or efficient enough to help you get work done, its svelte characteristics won't make up for that.

Enter the HP Elite Dragonfly two-in-one laptop, which is HP's answer to this problem. It's an ultra-slim laptop with a MIL-spec-tested design that weighs just 2.18 pounds, and it has the power and security features of one of HP's Elite series laptops. HP is betting on the idea that professionals will choose the thinnest and lightest laptop possible that doesn't compromise the performance or battery life they need to get things done regardless of their location—and that they'll pay top dollar to get it. We spent a few days with the Elite Dragonfly convertible to see how well-designed it actually is and to see if taking thin and light to the extreme hinders any necessities.
