Backstage makes it easy to backup the music library from your iPod to any Mac or Windows PC (requires Mac OS X 10. 3, or 10. 4, or Windows XP). In the event your computer is ever lost or stolen, you can rest assured that Backstage will allow you to recover your valuable music library from your iPod to another computer, quickly and easily. Backstage is also a great way to install your music on all of the computers you use at home or work using your iPod. Version 2. 0. 1 adds iTunes 7. 4 compatibility.
Backstage saved me when my laptop was stolen - I was able to copy my tunes from my iPod back to my new computer - including the songs I bought online! Best of all it was very easy to use.
Cons
Nothing - it worked exactly like they said it would.
