Wow, I've been incredibly pleased by the quality of the MSN Toolbar Suite. The guys on the team dig a heck of a good job!
For those of you who like me, annotate your digital photographs with JPEG metadata, you'll be pleased to discover that desktop searches will yield hits based on that metadata!
Also, don't miss the cool command definitions:
Type "=cmd" to bring up the command shell
Type "@whateveryouwant,commandToExec" to define your own.
