So I've recently changed mine to a different layout I'm pretty happy with. I ditched the Internet Explorer app with UC Browser, the built-in mail app with the MetroMail beta, and then I'm using the new InNote app for doodling and noting stuff.
The top tile is Super Calendar and then Vieather for weather.

Much less clutter than what I started with.
I feel like MS should implement wallpapers somehow. For instance, make the icons a bit transparent with a wallpaper in the back and the part of the wp that's covered by an icon would be blurred (like how the background looks when you pull down the notification center in ios7).
