Toshiba\'s Ultrabook somehow includes a sub-woofer, an ethernet port and three USB ports in a package that weighs a mere 1.1kg and is just 16mm wide at its thickest point. The miracle of micro-engineering comes at a cost, though: it\'s one of the flimsier Ultrabooks we\'ve looked at. It\'s not quite as powerful as other Ultrabooks we\'ve looked at, although it proved perfectly adequate for photo editing and was quick to boot up and shut down. Battery life impressed, too, and we reckon it\'ll last a full day of real-world use.
