An ultrabook™ is a high-end laptop, sleek in design but uncompromising in performance. Despite their slight frame, they have the capabilities of larger, bulkier laptops and some desktops. Ultrabooks are the new computing status symbol for the professional on the move. They cover a wide range of uses, have screen sizes that range from 13 to 15 or even 17 inches, and can cover broad price ranges. But be aware: Some computer resellers often refer to laptops as Ultrabooks when in fact they are not.
