Bing!

I never thought anything would wean me off Google, but I thought wrong; Microsoft's Bing is really a surprisingly good search engine. It's unobtrusive, useful, lighting-quick, and most importantly, gets me what I want. Previewing videos is awesome, as is the image search. Oh, and Wikipedia integration is equally fantastic; it's possibly my favorite feature. Heretofore no search engine has been as good as Google's, but we now have a true contender.

May the best engine win.

P.S. xRank is cool too.
