When you have I/OMagic's 52x24x52/56x CD Duplicator with LCD Display and USB 2.0, you have the best of two worlds. Using the CD Duplicator as a stand alone unit, you can easily copy music and data CDs. Or create your own music CD by combining tracks from different music CDs onto one disc. And MAC users rejoice Stand alone operation means you don't need Windows to use this as a separate disc copier.
