We had a chance to get up close and personal with Swedish startup Tonium's portable DJ unit and paw this 120GB-storing mobile mixing and more device. Comparable in size to the PSP (a smidge smaller), the Pacemaker's integrated crossfader and multifunction touchpad at first blush provide a surprisingly intuitive way to control your mix. We're not gonna lie -- we kinda wish the touchpad worked more like a Kaoss pad than like ye olde iPod scroll wheel, but all the same it's pretty fun to get some pitch bending on with a device that fits in one hand. Also let's be honest, you're probably not gonna become the hottest thing in Ibiza with this thing, but at $700 it's a relatively low-cost convenient practice setup for DJs on the road or an attractive option for aspiring amateurs. Be sure to peep yourself some video after the break.

Watch out NuMark, 'cause there's about to be a new product on the scene to challenge your iDJ line of mixers -- and not only does this one rock 120GB of internal storage to obviate the need for a pair of iPods, it's actually small enough to fit in your pocket. The upcoming Pacemaker from European start-up Tonicum -- set to be unveiled tomorrow -- promises to contain all the necessary features for bringing your mixing skills on the road, including a crossfader, dual 3.5-millimeter stereo jacks, direct-to-hard drive recording, and a multifunction touchpad for adjusting bend and pitch, among others. No bells or whistles like an FM tuner or color screen on this patent-pending player, but with both Mac and Windows support, we have a feeling that the Pacemaker is going to develop a small but dedicated following.
