The ZP80 ditches the built-in amplifier, allowing you to easily connect the device to your existing amplifier, home theater or the like using a optical or coaxial SP/DIF connector. The casing for the unit has also been updated.
Unfortunately still no support for Windows Media PlaysforSure Music Services or iTMS, but it will play non-DRMd WMA and a host of other formats. Both are specifically called out as “not able to be supported”. You can still connect an external source such as a PfS or iPod device and stream it around the house.
Still, this is a great step in the right direction of affordability and connectivity. Availability is slated for this Spring.
