Microsoft worked with Vodafone late last year to deploy Surfaces to a few dozen stores in several European countries (much as AT&T has done in the US), and one of those units happens to be set up at the carrier's IFA booth this week. The basic idea here is that each available model appears as a card that can be twirled, resized, and flung around the screen. When the software first starts, the cards start in a deck from which you can "deal" onto the table -- but when we first approached it, the Surface had obviously already been played with because the cards were in complete disarray. Not too helpful when you're a befuddled buyer
