We managed to get some hands-on time with a prototype unit running the Windows Phone 7 Series. While it is still in the early stages and there's still quite some time for the OS to reach retail units, we were duly impressed. The interface
was intuitive, and transitions across the various hubs were seamless. Tiles were adequately sized, giving our thumbs ample room to work with. As mentioned, we should be expecting devices powered by Windows Phone 7 Series by the end of 2010. In the meantime, if you like to see how the OS performs, here are a few shots of it in action.
