It was inevitable really: following the boom in Web 2.0 hype, canny product manufacturers are applying the 2.0 magic to, well, any object that’s a bit more advanced than its predecessors. As you would. Take the Wallet 2.0, so named because it uses refill sheets inside, like a Filofax. It comes with five of them, to hold notes, coins, ID and credit cards, with "more on the way" (i.e. to keep hatstands, small dogs, origami buzzards…). Whether it’ll appeal to men more than a classy, old-fashioned Wallet 1.0 remains to be seen. Hey, mine’s got a fancy clasp on the outside. Does that make it Wallet 1.3?
