What stood out to me is that images and videos are not being served up front and center on Google.
No doubt more and more people are searching for video. Google really looks old-fashioned in this match-up.
Compare that with Google's results https://img.skitch.com/20110211-r3jmccgi1ejs24p1hbdnu69fwm.j... (courtesy of xentronium). For this query Bing's results are far better that Google's (they actually specify circumference at equator and poles, alerting you that it's not the same; Google doesn't).
Also if you add (in meters|in miles) to the query, you get similar results to Google's.
DuckDuckGo: http://duckduckgo.com/?q=fantasia
I prefer uncluttered and informative results at the top instead of news headlines.
More than once I've spent time doing multiple searches for the answer of a tech question, re-wording the search to try and find a hit, only to have an a-ha moment and say, "oh! hey! '(original query) !g'" and bam, first page, The Answer.
I'm not aware of a way to do this from within google, which creates an odd situation: setting my default search to duckduckgo increases google's usability.
