Windows Live is revolutionary, or so claims Microsoft at least
I've never used Windows Live and I don't think I need it, but it seems fabulous.
Just look at its latest feature:
Browser back behavior (we're really excited about this one in particular :) )
Click on a search result, filters, pages and click the browser back to go back to your previous search results/state
Great, these guys have just invented the browser's Back button! 13 years later or something?
Ever felt like there was a problem with other search web sites?
