I think I can help here. Many years back, I am pretty sure I heard on the BBC that Bill (Gates) made a deal with the British government to give computers to every school in the UK. Now i don't think they are in any way mandated to use Bing, but I expect they are set up that way by default.
But on top of that (not that I count for much) all five of the PC's in my house have Bing as the home page, and certainly, my kids (aged 9 and 10) use it by default. they certainly KNOW Google and use it alot as well, but they are the next generation - and the pretty picture counts.
