Want an ultra sleek machine with enough battery life to keep you going long hours without plugging in? A new breed of “ultra portables” offers that and more. The lightning-quick storage on these units lets you resume work in seconds, even after they’ve been idle or asleep for days. The “best in breed” will cost you a pretty penny. But if you’re willing to spend a little, you can get premium features. Touch screens, full HDMI ports and eight hours or more of battery life are not uncommon. At the top end, you can expect a high-resolution 4K screen (3840 x 2160). Be extra-nice and Santa might even slip one in your stocking!
