Versora - Migrate settings and files from Windows to Linux
Here is a nice way to integrate a former windows user into the Linux environment. It's called Versora. They just partnered with Linspire (probably to gain more exposure) but they also sell to all other linux users.
Basically, it allows you to migrate settings, files, folders, email, wallpaper, network shares, and much more over to your linux desktop easily. The best part is that they don't charge an arm and a leg for it. It's $30, for either the download, or the boxed version, and is incredibly simple to use. Check out the website for a virtual demo.
