Harry Shum joined the Bing team in 2007, after eleven years with Microsoft’s research arm. The task at hand was enormous: catch up to Google. Five years on, Google is still the world’s dominant search engine — some estimates put its market share as high as 85 or 90 percent — but Shum believes that Bing has finally reached a point where it can compete with Google on a technical level.

If we all start using Windows 8 Tablets and phones I guess that Google’s numbers will fall.
That’s just a claim. Brand Google is too strong too be defeated so easily. Bing is still running in its Beta.
