The software's most impressive unique feature is its Hardware Independent Restore (HIR), which runs only from the emergency CD. With HIR, you can take an image made on one computer, restore it to another that has entirely different hardware, and be confident that the restored image will boot. You'll probably need to install sound and network drivers for the new system, but you'll be able to boot—a feat you'll rarely manage when you transfer an existing system to a very different machine. Also, you'll be able to use all your existing software and settings without going to the trouble of installing all your programs again.
