Nerval's Lobster writes "Microsoft's Surface Pro boasts one feature that could rapidly become an Achilles Heel, especially if Microsoft intends for the device to compete against Apple’s iPad and a host of lightweight Google Android touch-screens. In a Nov. 29 Tweet to a customer, the official Surface Twitter feed claimed: “We expect it [Surface Pro] to have approx. half the battery life of Surface with Windows RT.” That means Surface Pro will have roughly four hours of battery life. That’s roughly half the battery life (if not less) of Apple’s various iPads, the Samsung Galaxy Tab 10.1, Research In Motion’s PlayBook, Hewlett-Packard’s now-cancelled TouchPad, and Motorola’s all-but-forgotten Xoom. In other words, pretty much every tablet currently on the market. Nor can the Surface Pro compete with other tablets on price. The 64GB version of the device will retail for $899, with the 128GB version coming in a little higher at $999."
