I know dick about Apple, and its computers, but ever since the first Imac I have felt that Apple has been selling an image rather than a viable alternative.
They are a designer Computer, like a Ferrari, they cost too much, and you can never get to top speed except on the track.
same thing with a MAC, they cost too much, and they never prove themselves outside of the Lab.
But that is the market that they have found, and that is the reason why they will never grow past number two. Only so many people can afford one.
sorry guys but that is the way I feel.
