I really don't see what the big deal is. People, in general, like things like desktop backgrounds. If people's main compelling reason for trying/using Bing was the pretty pictures, I can not blame Google for giving most people the pretty that they want. Talk about an easy feature to implement. Seriously how many power users actually use the Google homepage. I for one can not remember the last time I saw Google's home page. If you do not want pretty Google, revert to original Google.
