NEW YORK -- Microsoft on Monday unveiled an update to its Surface tablets, both the full-Windows Surface Pro 2 and the stripped-down Surface 2.
The RT version contains a Tegra 4 chip from Nvidia. It also features a full HD 1080p screen and runs three to four times faster than its predecessor. At the same time, battery life is 25 percent better than the first Surface.
Sales of Microsoft's first Surface tablets -- the Pro with an Intel chip and RT with an Nvidia processor -- have been dismal. Microsoft had to write down $900 million for Surface RT in July, and the software giant later revealed it had generated only $853 million in revenue from Surface RT and Surface Pro since their debut last fall.
