This bizarre thing is the M1X-DJ, a product Philips has produced with help from middle-of-the-road trance master Armin van Buuren. It's 80-Watts of power you can carry around with you on a shoulder strap, DJ-ing to anyone not fast enough to run away.
You plug your iPad or iPhone 5 into it, or anything else Apple-friendly via a Lightning connector or even a Bluetooth link, then mix tracks and playlists together from your various linked hardware using Algoriddim's djay 2 app. It's the iPhone docking speaker of the gods.
And in a rather interesting throwback to the boomboxes of yesteryear, the thing can be powered for up to five hours from a bunch of good old D cell batteries, should the "party" be happening somewhere without power. Say, for example, in a field. On your own. [Philips]
