If you prefer cheaper computers, buy a used one or two generations back model. Simple as that. Better than buying crap just for the psychological satisfaction of having something "new".
Normally I would agree with you, but having owned both I disagree. I think the latest generation of Macbook Pro's are just heads and tails above the older generations.
Crap people buy crap computers. They aren't even thinking about it. It's like they don't think they are worthy enough, and so they're jealous of those of us with more Self esteem.
