In a briefing with the website, Greg Sullivan, senior product manager for Microsoft told that
“The search engine has been heavily integrated into the OS, so it would be hard to offer an alternative”.
Sullivan clearly said that while Microsoft will allow other search engines to create an app or hub for themselves for Windows Phone 7, but it will not be letting any other company (we also presume Google) to be the default search engine in the new mobile operating system.
If we compare this to the iOS 4 from Apple, it appears to be more generous for it had actually added Bing with Yahoo and Google side-by-side, as an option for search engine on the phone. Sullivan expressed that the move is because of “Tell me” integration which would allow users to search the phone as well as web by use of voice commands. This “Tell me” feature would try to copy the Google’s voice recognition feature on Nexus One or Apple’s voice control on the iPhone.
However the company tried to justify this move, but we do not agree. Microsoft, as always is trying to make the things a closed system. On the other side it should think from customer’s focal point, and letting them decide, choose and use what best suits their needs. Or else, we cannot guarantee that the feature would be taken happily by most of the users of Windows Phone 7.
