What the hell were the designers thinking?

I had noticed that Microsoft started placing a huge start button, contacts button etc on the bottom. Now the bar on the bottom has doubled in size and the there is space left on the top bar.

Why Microsoft -- why? That's one of the main reason I steer away from new rom updates. I like the two bars (top and bottom) to be as thin as possible like in 6.5. I can't believe the Chefs are embracing this ridiculous and pointless design update (which rolled out long time ago).
