Ugh. The expensive computers aren't their downfall, they are their business model. Say it with me, folks: "Apple is a HARDWARE company." OS X is a value-add, maybe the biggest one in history, to sell more hardware. They don't make cheaper hardware because enough people will buy their expensive hardware to keep them profitable. Apple doesn't make discount computers for the same reason you can't buy a Cadillac subcompact: they are a premium hardware company. Making cheap computers will cut into their profit (why make $50/computer when you can make $300/computer?) and turn out crappier 'value' Macs, further diluting the brand. For the same reason, they don't offer OS X for other platforms. It's designed to sell their hardware. Selling it for PC eats into their hardware sales while upping the numbers of people who install OS X inexpertly or on wacky hardware and then decide it's unreliable.
Rate this -1 or +1, but make sure it says 'Obvious'.
