Microsoft recently posted a short 1:22 video clip that provides a much closer look at the brand new Start screen that we can expect in Windows Phone 7.8 and Windows Phone 8. Microsoft's Ben Rudolph walks us through a beta build of the new Start screen on his Lumia 900 and shows how to quickly resize Live Tiles between small, medium and large sizes.

Rudolph's blog post, which accompanies the video, also suggests that Words with Friends and Draw Something might be launching sooner than we think — he said the apps are "so-close-you-can-taste-it." Be sure to check out the video above — we're definitely excited for Windows Phone 7.8 to land on our Lumia 900.
