Microsoft starts pre-orders for Surface Power Cover, ships March 19th
Microsoft has opened up pre-orders for its Surface Power Cover, with shipments set to start on March 19th in the United States. Spotted by ZDNet in the Microsoft Store for $200, the Power Cover adds up to 70-percent more battery life to the Surface Pro, Surface 2, and Surface Pro 2 tablets, and retains the same keyboard and touchpad as other Surface covers, though it adds 9.75mm (0.38 inches) and just over half a pound in weight to each tablet.
