We were really impressed by Microsoft's fancy new Start Screen for Windows Phone 8 -- heck, it could even be the best home screen ever. Now you can see why, as Microsoft's showing off an early version of Windows Phone 7.8 on a Nokia Lumia 900.
I'm a big fan of the resizable tiles -- smaller tiles are better for me, with the odd large one for at-a-glance information. It's just a shame current Windows Phones like Nokia's Lumias won't get full blown Windows Phone 8, but at least Windows Phone 7.8 looks like a pretty good stopgap. [Windows Team Blog via Ubergizmo]
