Microsoft Senior Product Manager, Greg Sullivan, has confirmed with Pocket-lint that Windows Phone 7 is pretty much glued to the Bing search engine. Third-party search apps will arrive but it looks like they’ll probably be standalone as the OS and Bing seem to be fairly tightly integrated throughout. Greg states..
“The search engine has been heavily integrated into the OS, so it would be hard to offer an alternative”
So, it’s becoming clear that Windows Phone 7 is a pure Microsoft phone. Microsoft services, Microsoft music, Microsoft games and Microsoft search. If you want to customize it with other stuff well, you can – but not completely.
Update – There’s some preview shots of Bing in action below, or check bing.com for more.
