I've never really been a mac fan. I will admit, mac makes some fairly decent, and attractive computers. I'm personally fond of the look of their macbooks (though i think it would be better if they had a wider color selection), and although i'm not too familiar with the operating system, i'm sure it has it's strong points. However, a cool looking computer isn't worth the extra few thousand dollars (that goes for you too alienware). My Dell laptop looks pretty nifty as well, and It was sure a lot cheaper than a comparable macbook. It drives me mad when people claim that mac's are better than PC's, because they are "super awesome, and perfect, and purdy". There's also a misconception that Mac's can't get viruses. In fact, today in my psychology class we had a guest speaker come in to talk about internet safety. He commented on how "No one gets viruses on macs, because since most businesses use windows, hackers don't bother targeting os x, and there probably won't be a threat for 10 or so years." It's a computer. No matter what operating system it has, it can still get a virus. Hell, they already have viruses, Google it. Os X has it's fair share of security issues. And if you think hackers only target businesses/corporations then you're just plain ignorant.
That being said If you own a mac i'm not calling you ignorant and stupid, and all that. (i know you're out there. 12% of my pageviews are from Mac :b) Some people have the money, and don't mind spending it on a mac. Some people like the Mac OS, and the looks of their computer, and all that jazz. Thats a personal decision, and you should do whatever floats your boat. I'm just saying do your homework before you buy, and educate yourself. Then when someone asks why you bought a mac, you won't infuriate them with an ignorant answer like "it doesn't get viruses" or "It's the best computer out there". Additionally a few hours of research could save you a few Thousand dollars if you find buying/building a PC is a better route for you.
I stumbled on this image while wandering aimlessly through the internet today. The only issue i found with it is the raid card comment. There are raid cards on newegg for up to 3000 dollars. However, i highly doubt the "Macbook raid card" is comparable to that model (i'd have to research the specs of the card they offer), and i'm sure a cheaper model would work fine. Additionally the amount of people who actually require a raid card is pretty insignificant. Everything else they mentioned is pretty much spot on. You're getting ripped off.
