Microsoft Surface will be making its debut commercial appearance at AT&T stores in four trial cities starting 17 April 2008. Surface is a 30-inch table display that combines touch, gesture, and device recognition. I've seen Surface from a distance at various events — it has been impossible to get any closer than about 12 feet due to the crushing mass of geekdom it always attracts.

AT&T will conduct a trial of Surface at selected stores in New York, San Antonio, Atlanta, and San Francisco, and then evaluate deploying throughout its 2,200 US stores. The announcement was made at CTIA Wireless in Las Vegas on 1 April 2008. Keep your finger on the pulse of the Surface at their team blog.
