Microsoft have released a new MSN Toolbar for IE which as far as toolbars go looks pretty cool. It seems more like a snazzy RSS agregator, with added search facility.
The toolbar as well as having the RSS streams for various content areas such as news, sports and autos. It has the ability to know when a user has done a search using any of the search websites such as google, yahoo! or Live and using the search parameters does its own search using Live and aggregates the results such as news, images, and websites into the toolbar so that the user can jump straight to the live results if required.
The toolbar has been created using Silverlight, however it is currently only supported by Silverlight 1.0. Which means it wont currently work for all us eager dev's who have installed Silverlight 2.0, however a SL 2.0 version will be realesed soon I hope.
Channel 8 offer a really good video walk through of the MSN Toolbar and some of its features right here.
