How many of you out there are already ATRAC converts? I am contemplating converting my entire library of MP3s to ATRAC. Since I have a Sony NW-HD5 and a Sony VAIO notebook that hosts my library - plus the fact that I use Vaio Zone & SonicStage for playing back music - I figured I should convert to ATRAC, seeing how DSPs only work with ATRAC tracks. I have some considerations in mind, though: 1) Should I upgrade to another VAIO notebook, will I have any problems with transferring my entire ATRAC library from the old to the new? Will there be any DRM issues? 2) In the event that I eventually switch to a non-Sony DAP, how difficult would it be to convert ATRAC tracks back to MP3s? 3) Are there any restrictions burning an audio CD from ATRAC tracks? Or am I just better off keeping my library as MP3s?
