You sound just like this apple fan boy I work with. He thinks apple can do no wrong. Seriously dude get a clue, those parts aren't any more high quality than any other OEM. They all use the same freaking chipsets and parts. There is nothing of higher quality. All apple products are just over priced stuff that's just made with Chinese slave labor. And before you say apple is moving its manufacturing back to the USA, they are only doing that because its getting to be cheaper to build some of it here than over seas. Also more people are looking at the whole made in the USA tag thing because outsourcing is giving away American jobs.
Couldn't be more wrong.. it's not just about the components, there is more to apples pricing than components.. they have a premium keyboard, mouse, solid aluminium, unique designs, beautiful glass displays and so on, it's all comes at a premium, if non of that stuff does anything for you then yeah you'll think it's over priced but for people than do it's well worth the money for a nice solid quality machine.
Why do you think there is no direct competitor to the iMac?
