As technology moves on & storage becomes less of a problem, file size will be less of an issue and digital data quality will increase. There are already lossless formats such as FLAC and mp3's can already be compressed at higher data rates for better sound quality.
Add to that the likelihood of another new technology in the data formats and you'll probably find that by the time physical disks finally disappear, you won't miss them. There's still the chance that AudioDVD could take off with the introduction of hi-def or we may even see portable music seen a completely different direction with video player taking precedence over audio only recordings.
Bowlfreshner's final comment about vinyl and CD's is absolutely the first time I've ever seen anyone make that argument for CDs - vinyl yes but nostalgia for CDs...
Now I really do feel old.
