I have to admit that I’m prejudiced against Microsoft. I got rid of my hotmail account ages ago and haven’t looked back. I’ve used nearly every major search engine but live.com and didn’t even realize that Microsoft had redesigned their search page or that they offered so many search options.
This is why prejudice is bad – live.com actually has a pretty nifty book search. It’s a bit different from Google’s and I’m liking it. They also have an academic search (comparable to Google Scholar).
Long story short … don’t be prejudice … you might miss some useful tools!
