You’d have to actively be avoiding the tech media over the past several months not to have heard about Ultrabooks. Their coming has garnered a boatload of buzz, fueled in no small part by Intel’s $300 million fund to get hardware and software makers behind the cause.

Ultrabooks are Intel’s answer to the spread of ARM-based tablets—a way to capture the hearts and minds of the masses with an x86-based portable device (of the Intel persuasion, natch). To that end, Ultrabooks are required to meet a few key “desirability” standards. They must be slim, lightweight, have generous battery life, and boot and resume from hibernation in brisk fashion. It’s also understood they should look cool. As Apple products so clearly demonstrate, style sells. And sure enough, Ultrabooks—at least those that have debuted so far—are heartily infused with MacBook Air influence.

So are these new, “cool” devices the next must-have products? Is all the hoopla warranted? We review the first four Ultrabooks to kick off the category. All are 13.3 inch models, but each brings its own brand of hot-newness to the table, with varying degrees of persuasiveness, as you’ll see when you click the jump.
