Last night I was at a party with my wife. People were taking photos with their phones. I pulled out my wife's 920 and took a bunch at the same time. Today, everyone shared their photos. The 920 absolutely killed the other phones (mostly Android). They kept asking my wife what camera she was using. When they heard that it was her phone, they wanted one ("I want that phone, the 920"). Fortunately I had talked to my wife about the Nokia Icon a few days ago, so she told them to get it instead of the 920.
I hope that MSFT continues the excellent photo capability of the Nokia phones. I think that there's a huge opportunity for WP to gain marketshare. People have been impressed with the texting, internet, location, and limited photo capability in smartphones. Now that the hyper-growth phase of smartphones is slowing, people will be more demanding of the photo capabilities in the future. It will be an important differentiator.
Note: Now that MSFT owns Nokia I wish MSFT would take WP proprietary. Forget trying to get other OEMs involved. With fewer hardware targets to deal with they can optimize the hell out of the code. That'll result in better power consumption, better performance, better integration of hardware innovations, etc. I think it'll help with carrier approval of updates, too.
