The reaction to Apple's announcement shows that it hit the mark very well.
Suddenly, the Wintel world is on the defensive and they will grab at all sorts of straws to explain away the news - just like the Apple fans did when they were on the defensive until yesterday.
We will hear about flawed benchmarking, false advertising(like Intel did not do it the MgHz myth), pricing manipulation(like no one else does it), and so on. The reality is... evolution. The 32 bit replace the 16 bit and gradually the 32 bit will give way to the 64 bit.
I am sure that no Wintel supporter will change their mind over the G5 claims but they will hurry to buy the next Wintel machine sporting a 64-bit capability.
Cheers mates, thanks for making my day.
