Now that every browser includes a search bar next to the address input, why go to Google's home page at all? I very rarely do so.
Basically, I have found very little difference in Google and Bing's search. They are both equally functional and fast. If anything, I've found that I have no reason to switch back to Google - Bing's daily rethemeing adds a little spark to my day.
I encourage everyone to try this for a week. You'll be amazed at how undifferentiated the two major search players truly are at search. These little user delighters are going to be a huge component in the battle for search revenue in the near future.
