Although it won't be available until spring at the earliest, Microsoft is continuing to take prototypes of its touch-screen Surface computer on a worldwide promotional tour. Some of the key cities already visited have included New York, Toronto, Paris, and Zurich.

Graffiti artist James de la Vega shared the Surface with a couple of kids at New York's Sheraton Hotel this summer. Next stop is Boston's Sheraton Hotel on Saturday.

Microsoft had hoped to put its tabletop computer on the market this month but now is hoping to have a final version ready by spring.
