I’ve found a new object of desire which, once acquired, I would probably never use. It’s this OB-4 “magic radio” from Teenage Engineering, a design group that creates tech with a playful but premium approach. This wireless speaker not only looks lovely but has a handful of really interesting features, the most interesting of which has to be letting you, at any time, rewind up to two hours with the spin of a dial.

The truth is I rarely would require the rewinding feature, which seems mainly useful for catching a bit of a podcast you missed or, for those of us who still listen to FM radio now and then, going back to hear the DJ say the name of an artist or piece. You can also slow it down and presumably scratch a bit by spinning the little circle, though again it’s probably more fun in theory than in practice.
