Not that this’ll ever replace a real DJ set up (at least for anyone that takes their craft seriously), but I must say that I wanna get my hands on one of these. Looks like at least a few hours of fun packed inside this mobile mixer. You use it with your iPhone, iPod touch, or iPad. The mixer, by IK Multimedia, features a crossfader, cues, EQ and volume controls, and works with a variety of iOS DJ mixing apps—as long as there is a tempo matching and beat syncing function. If you really want to nerd out, Engadget did a pretty in-depth review of it. Here are a few videos they did and you can read the full review here.
