It seems that while bing has picked up popularity in the SE wars it may not be as unbiased as one would expect from a SE.

Here is a fun little test you can do on the phrase: ‘Why is Windows so expensive?’ One would expect that this would return at least some results about the expensive Windows OS. What you get instead is a full page on ‘Why are Macs so expensive.’ In the event that you don’t want to try this lab experiment I have taken the liberty of print screening the results.

At least Google isn’t biased.
