Toshiba is launching its second foray into the netbook market, with the 10.1-inch Dynabook UX netbook offering. The Dynabook UX-series netbooks are based on the Intel Atom N280 chip and come with 1 GB of DDR2 memory, a 160 GB hard disk drive and integrated GMA 950 graphics from Intel again. The 10.1-inch LED backlight display boasts 1024 x 600 pixels native resolution. The Dynabook UX comes in two colors - brown or white, and a choice of batteries - a standard battery that will last for about 4 hours, or an extended battery that could provide up to 10 hours of use. Microsoft Windows XP Home OS comes pre-installed with the netbook. The UX-series computers will be launched in Japan on Friday for around ¥60,000 to ¥70,000 (US $606 to $707), and follow in other markets later this year.
