This makes me sad, as it's my primary gripe with Amazon Prime. The only Prime service I actually use is free 2-day shipping. But they keep lumping more and more stuff in there -- video streaming, movies, photos, music, etc -- and the price keeps going up. Sooner or later it's not going to be worth the free 2-day shipping and I'm going to have to go back to paying for shipping and waiting around for stuff to arrive.
I'd be very sad if Google decided to emulate this :(
