I like Live.com and Live Search a lot - they have come a very long way since first jumping in to the playground and with subtle tweaks along the way search now has pride of place as my preferred search engine in IE7. My main gripe is it could still be quicker and make better use of AJAX but for now I'm using it 90% of the time over Google as you never know when SteveB is gonna appear behind you :)
