About a year ago, I jettisoned my relatively heavy Windows laptop for an 11-inch MacBook Air that weighs only 2.4 pounds that I favorably reviewed. Now Apple has some competitions from laptops ultralight laptops, called “UltraBooks,” that run Microsoft’s Windows operating system. Samsung, Dell, HP, Lenovo, Toshiba and other companies are offering their own machines, often weighing 3 pounds or less, that offer all the power one needs from a laptop in a much thinner and lighter form factor. Most of these computers use solid state drives that boot faster and take up less space (and use less energy) than hard drives but store less data. Screens range from 11 to 15 inches and unlike the Netbooks from a couple of years ago, Ultrabooks typically have full-sized keyboards.
Here are CNET reviews of some of the leading Ultrabooks.
