This is a preview of new Microsoft product later this year Windows Phone 7 at New York City, Vin Rock press event.
There were a couple of Microsoft representatives showing off Windows Phone 7 on prototype hardware. The devices seemed a bit thick, but we hear the real phones that you'll be able to actually buy later this year will be much nicer. The venue had some issues with network connectivity so you may notice some slowness on network-dependent features like Bing maps, but otherwise, the new operating system is looking to shape up very nicely. The Microsoft representative mentioned that he flashes new builds every day yet is still using the device as his personal primary phone.
