Apple computers are honestly built NO better than any other machine on the market. You could easily get a Lenovo, XPS, Sony, and one of several other notebooks that would beat the living shit out of a macbook pro and cost far under $500 less. Hell, virtually all products branded by apple are out sourced by other companies. You ARE paying for the logo. Period.
If you really are sold on OSX, which is proprietary garbage, use some form of linux. Ubuntu has no viruses, is free, and simple enough for the naive apple user to come to terms with.
Mind you, I HAVE a Macbook. The only reason I own it is because I had a friend getting rid of it for an absurdly low price. Don't claim that I haven't used one nor have an idea of the niche they claim to cater for. Apple prays on those too lazy or stupid to buy computers that will hold up just as well with the same performance with the false notion of a better product.
