At the end of 2010 Microsoft launched its fresh new Windows Phone 7 smartphone operating system, and the initial reviews were quite positive. These devices were all vetted by Microsoft to ensure that they comply with their rules on things like hardware design, buttons, shape, etc. Problem was, with all this control, the resulting devices were pretty similiar to each other. Sure, you could find some specification differences between them, but there was not any that stood out from the rest. But Samsung waited a while and released a Windows Phone device which not only looks better, but performs better than the other WP7 devices.
