I'd never heard of the Bing version of this, but you guys are right, the quality of the areials are awesome!
I just messed around with it for about 10 minutes and my first reaction is that I think that I like all the features of Google Earth better than the Bing version, but the birds eye view of Bing definitely blows GE out of the water!
Thanks for the heads up!
I had the same issue as TPH when I first started looking at it & it wouldn't let me do the birds eye view. I zoomed in a little further and then it let me do it just fine. Maybe try that.
