After running the Google toolbar for a long time, I switched to the new MSN toolbar with desktop search on my work machine.  After using it for several weeks, I can attest that this is a great package of software and it's still only beta!  I'm now installing it on my home machines -- that says a lot as I prefer to run very clean and tuned systems at home.

Here's why I chose it over Google:

• Hotmail, Messenger and MSN spaces integration
• My MSN integration
• Form Fill -- finally, the web toolbar people are following Mac IE 5 innovations introduced in 2000!
• MSN search beta integration - this is on its way to becoming a serious Google competitor.  It's not there yet, but it's good enough for me to use it over Google now.
• Page viewer and highlighter for search terms
• Desktop search works as well or better than Google desktop search.  The Outlook integration is killer.
