Cast your mind back a few months and you’ll remember I was quite a fan of Tonium’s portable DJ-ing device, the Pacemaker.

This new music-focused mobile from Samsung squeezes in a remarkably similar set of virtual turntables for mixing your MP3s on the go.

Sadly, while the phone’s audio quality, courtesy of Bang & Olufsen, is as good as you’d get with a Walkman handset, its unresponsive touchscreen and Samsung’s cumbersome TouchWiz user interface ruin what could have been a cool device.
