Crappy rotating background images are not a feature. I always remove them from every product, desktop, tool I have. I will NOT be "wondering what the fuss was" in a month.
Maybe I'm inferring too much, but your use of "crappy" and capitalising "NOT" suggests to me that this feature makes you angry. I think it's worth considering whether your reaction is a purely logical one, or partly an emotional one.
If I open up a law firm and then the decorator puts a gigantic mural of H.R. Giger's work on the walls, I'd probably be less than happy, and not because of emotional reasons (although it would be pretty creepy). It'd be bad for business.
Similarly, if Google's new change increases load time or distracts me...
