Windows 8 Start Screen is flat and boring.

I just decided that I needed to step back and take a hard objective look at what professional UI designers have been telling me about this. The fact is:

is boring and flat. Look at the stock app tiles like IE, Weather, Stocks, Settings. Just a pastel background with a simplistic white glyph. Microsoft could have invested in some beautiful rendering instead. We know they have the talent from Zune, XBox dashboard and other things. I know Microsoft is trying to make UI as flat as possible to save battery on tablets, but when you take minimalism TOO FAR you take away from the visual UX in favor of the battery life. It's unbalanced. Maybe a Surface will have more battery life then an iPad, but if the user experience is not enjoyable will people care?
