Bing Maps Launches Streetside

I am a big fan of Google, I use Google stuff all the time, like Gmail, Google Search, Google Maps. I know we have some other choices, like Microsoft's products, Yahoo Mail, so I like to try them, and compare to each other. Recently, Bing Maps launches a new feature: Streetside. It is similar with Google Street View, but still has some differences, like 360 degree view. Unfortunately, Streetside only available few major cities in US and UK, but it worth to try.
