I live in The Netherlands. That is in Europe. So I am European. And I can speak as one.
You could also say that for example 90% of all Texans use Bing, but only 5% in California for example.
Here in the Netherlands it doesn't "feel" like it gets used, so I wonder what the European totals are. The Netherlands could be the hypothetical 5% and France the 90%, who knows.
Is it that hard to understand?
And why on earth do you think Bing equals Microsoft? I'm talking about the product, I named it by its name. I'm not talking about the company that created it.
