Kwasi,
as someone who has worked in the search engine industry.. trust me, MS has tried to take the search crown many times before... This is hardly their first attempt and they have lost every time...
Someday they might get it right, but forgive me if I yawn and ignore this latest supposed gauntlet.
The difference here though is that MS can't use their OS monopoly to play dirty pool. They have a less than stellar record when it comes to level playing fields.
Mind you, this is coming from a guy who would live with an abacus and a slide rule rather than touch a Mac. :P
