Google Maps layer

What do you guys think about this Google Maps layer, @vincentlaucy @hupili @2blam @clacanzo?

Pros:

 - So much cleaner and easier to digest

Cons:

 - The zooming is kinda weird because the geojson layer is kind of out of sync
 - Seems to use more CPU?  My laptop's fan gets louder when I use this map.
