Here's a Microsoft Surface demo with Bill Gates himself: Microsoft Surface is an interactive coffee table shaped computer that responds to your touch and items that have special bar codes attached to them. The machines are set to be shown this Wednesday at a technology conference in California and then will be initially released in November at US stores such as T Mobile and at special properties owned by Starwood Hotels & Resorts Worldwide Inc. and Harrah's Entertainment Inc. The Microsoft Surface computer is expected to cost between five and ten thousand dollars per unit. There are expected to be a small number of programmes included with the Surface computer which include a programme to help share digital photgraphs between friends and family.
