Pioneer has teamed with XM to create the portable XMp3. The Music Manager will hold up to 100 hours of XM programming from their satellite radio service. Manage it with software, record up to 5 channels simultaneously, check out highlights, and preset channels. Add a microSD card and store MP3 or WMA files. You can also bookmark and purchase tunes from online music services. Users will also like the feature that automatically buffers the most recent half hour for easy replay. The XMp3 weighs only 3.1 oz. and is available for $249.99 after instant $30.00 rebate.
