Dave, one thing you may wish to think about is having a mirror back-up of your whole C drive (one each for the laptop and the desktop) because hard drives crash - I've been through two C drives within 15 months - both Western Digital 10,000 RPM Raptors installed in a Dell 690 Precision Workstation. After the first experience, I bought a copy of Acronis True Image Home, created the boot CD-ROM using this program, and then creating a mirror of my C Drive on an external USB drive. I kept up-dating it periodically. Then after the second C Drive crash, all I needed to was to replace the drive and do a system restore with the Acronis boot CD and the mirror on the external drive. The process ran itself automatically (for about 4 hours) and was completely successful re-instating absolutely everything as it was based on the most recent back-up. No software had to be-registered because as far as the system was concerned nothing had changed. Highly recommended. It is the PC "equivalent" (but still not as good) to Apple's "Time Machine" for the Mac.
