Having an application reinstall fest with your new computer is probably in your future. If you use Outlook Express for your mail, be sure to move your mail data.

Consult your browser's online help for more information. Smug Mac users can drag their applications and drop them on their new machines. Then drag and drop preference settings from the Preferences area in the system folder. In every case I can remember, this has restored my preferences without issue. Some Mac applications put files in the System Folder and those will have to be reinstalled on the new machine, just like in Windows.
