Here are some pictures of a concept iPad DJ station. It shows that the iPad can be a great musical tool. We've seen similar designs use iPod Classics, but the iPad's large touchscreen adds a new dimension of interactivity.
Look at the keyboard with the waveforms of the tracks below it, or the faders on the iPad's touch screen. Sadly, it seems that the machine is simply a concept, probably put together in a CAD program or some 3D software. Still, it looks cool. Let's just hope the DJ doesn't spill their drink.
The iPad is indeed a cool music machine: See?
