After discounting the Surface RT tablet worldwide by 30 percent, Microsoft is now cutting the price of its Surface Pro tablet by one hundred dollars. Steve Ballmer himself has recently declared that he was unhappy with the number of tablets Microsoft has managed to sell. The price cut offer is valid between August 4th and August 29th. It might continue or stop, according to the supply. The price cut is applicable to Surface Pro 64 GB & 128 GB models."
