I have the bing home page set as my browser home page.  I like it as when i launch my browser i usually get a nice looking and informative image every day.  It looks far better than the outdated google home page and i don't see a reason to set your own one.  I like seeing what the bing team has come up with.  Also the bing pictures are often related to the specific day eg on halloween they might show a pumpkin etc and with the information points it can be quite educational.
