It's really interesting that Google seems to be at times able to pull off wonderful UI design bordering on genius (Chrome, Google Maps) and at other times just barely able to be at par (most of Android with select exceptions). I guess this just reflects different teams within Google, but it's a shame they can't apply their best UI talent across all their products (and particularly, the products that most need it, like Android).
I was thinking more along the lines of exception to the rule. I honestly have some trouble finding another product by Google which has this attention to detail (design-wise), maybe Chrome...
