Not because of how much it costs necessarily but mostly because it determines your level of education and knowhow.
For instance, a Lexus is a car for sheepole with little brains. Why? Anybody who understands engineering know a standard Lexus is a $42k car that should cost $25 because it is a Toyota with an "L" badge.
On the other hand people with education and brains know a $42k BMW should cost $42k and will go into detail as to why it is a 10-times better car than Lexus. This is and absolutely accurate statement and it is information above and beyond what is available out there from car reviews, which most of the time spill nonsense that fools everybody except for people who are the true experts.
It is all about education, about class, about your level.
Same thing with computer. Sheepole and the average joe will say a PC is better because, well, software is about the same and it is cheaper and offer more features.
A person with knowhow and a high level of education will point out that for all the metrics that matter: depreciation rate, overall experience and productivity with the computer, mac wins by an undisputable margin. Whereas all the metrics that do not matter: price, features, the wintell box "wins". You see? There is a huge difference, but it is a subtle one and I have already tried to explain it to you people with no luck. It seems that you lack the basic software to understand.
Everybody who really knows their computing agrees with me 100%. But to realize this you need to be above average intelligence, be knowledgeable, and have good analytical thinking.
