I've just visited a customer (large hospital), where the IT manager (an absolute Windows supporter in the hospital), admitted that she had bought an iBook at home. She will put Windows on it, but is for the moment playing with OS X.
This is definite a person that would never have bought a mac 10 months ago.
So yes, I think they will sell a lot of these machine.
Advise: buy Apple stock, at the price it is now, it really is a bargain.
