Didn't know about the differences between CDs - my husband (network architect and complete computer guru...) said there were no differences! I see he was wrong now.

Agree - lots of ways to share data now.

When I was transferring my files from PC to MAC it was getting harder & harder to copy to DVD as backup and storage. I kept getting weird error messages. So I finally broke down and bought a 160GB portable hard drive. I used it to transfer files, and now am using it for file backups.

thanks all for the info!
