I'm not going to get this, mostly because I've got all the music-based equipment I need.  Space is an issue.  Also, the songs.  Mixes, dance stuff, techno-ized things, I just don't like that style of music.
I think it's got long-term potential, though.  The biggest question is if retailers will keep a few in stock all the time for people who decided to pick it up months down the line.
