Also keep in mind Bing is a start. It's a change to the brand name timed with some fairly significant technical refreshes and some obvious ideological changes about search.

There is a lot more to the space of "search" as we move forward into the next decade, much of which Google, Yahoo and Microsoft haven't even tried to move forwards on. Hopefully the kind of technology and infrastructure related to search will start to be re-purposed for other uses.
