also, you state that 90% of the companies have switched... but I really REALLY doubt that.

most companies will wait before switching. one of the reasons would be the high cost of new licenses, aswell as the costs of changing the infrastructure.

also most companies KNOW that Vista support is still very low...

somehow I doubt even 40% of all companies switching already.

then again, I have seen no numbers anywhere yet stating either way. just seems very unlikely to me.
