I new some one would get on here and complain about Google having streetview first.
I think the integration of photosynth is very slick. A little disconcerting to think you might just happen to be able to look in side some ones home.
edit: i just took a test drive of the new bing maps site. i enjoyed it very much. Still a couple things i would like to see done with photosync but for the most part very cool. I think this is one that 'marketing' should get a hold of and share with as many people as posible.
