Having already taken Samsung's Beat DJ for a spin, the mixers at Engadget Spanish tried out its not-quite-finished younger brother, the Beat Disc. The two handsets are pretty similar, with the most notable differences being a slide-out keyboard and the Bang & Olufsen speakers placed closer together at the bottom of the device. All in all, it comes off as a cheaper version of the DJ, so take that as you will. Check out the moving pictures version of the hands-on after the break.
