Desktop Search

Google Desktop Google has done more than just conquer the Internet -- with Google Desktop, it has conquered your PC as well. The program brings the same kind of fast, accurate searching to your desktop that Google does to the Web. It searches as you type, and displays the results in your browser. One nice touch: When the program is installed and you search via the Google Web site, the results will also include those from your computer.

Backup and File Synchronization

That's not the case with Mozy, a full-featured online backup service. You can, for example, back up only the portions of files that have changed, saving considerable backup time and space. You can also browse through 30 days' worth of backups to locate previous versions of files.
