Nice job picking out the only quote in the entire thing that suggests Macs are more expensive. You can buy a PC for less than Dell or anyone else charges too if you buy the components yourself. If you actually read the article (instead of deliberately taking out one quote that runs counter to the rest of it) you'll see that between the comparisons they did, the Mac is equal to one system and $200 less than the other. When the components were priced out separately to build a Mac Pro clone, you could save a whopping $5.67. So while they say there's little doubt you could get one for less, they don't actually manage to, and the quote you chose runs counter to the entire rest of the article. But then, that's why you chose the quote, since there's no actual evidence anywhere of Macs being overpriced besides statements from PC fanboys. They don't offer any real budget models or anything, but that's far from the same issue. Personally, I see the value in Macs, it takes a lot less effort to keep it running well for a very long time, and the fact that most people hear that and say you've set your computer up wrong only proves that point. I have two at home that we use regularly, and they're great. But, I also keep a custom PC running Windows 7 for gaming, because it is definitely easier to upgrade than even the Mac Pro and I don't have to wait for ports. There are definitely many pros and cons to each side, but the price isn't really an issue for Apple unless you're only trying to buy a budget system. It's really only fanboys who still say it, and the fact that you deliberately took that one quote out of context knowing what the rest of the article contains suggests that's all you are, continuing on even when you know you're wrong.
As for $7-10k being an absurd amount for an individual to spend on one computer, I'm aware, you'll see I already pointed out most people wouldn't notice any benefit from doing so. However, like I said before, if you're a criminal and you know you're not going to pay for it, why not go all out?
