Microsoft Shows Off Windows Phone 7.8, Resizable Start Screen

Windows Phone 8 may not be coming to Nokia's Lumia 900, but Windows Phone 7.8 will be. The company had to make the tough decision to cut-and-run in order to make WP8 the best that it could be, but the good news for early adopters is that WP7.8 brings a lot of the same visual elements to older devices. The new Start Screen is arguably the star of the WP8 show, and that's one of the things that will make the transition to WP7.8. There's the ability to resize the start screen, change the size of tiles, and make the things you care more about... more visible. These things generally tend to have a better impact with video, and that's exactly what's below. There's still no set release date for WP7.8, but keep an eye out -- should be here by fall at the latest.
