nice and ugly

I wonder if this is really Rhapsody To Go compatible? Most users and even reviewers seem to confuse their streaming service ($10) with the "To Go" service ($15), which is an all-you-can-eat subscription download plan. Rhapsody and Napster implement the later via PlaysForSure (WMA 10 DRM), but Rhapsody also has their own system for subscription downloading (used with a few Sandisk PMPs). Of course, this service is only available on and through Windows. It would be interesting if Rhapsody has licensed their To Go service for use on a Linux device.

It looks like an ipod rip off! something like a company in China would do
