I think that the one thing everyone has to realize is that Macs ARE overpriced.
I think the one thing that you have to realize is that the ideal price for a product is that which will yield the maximum profit, not the lowest price. Apple has a responsibility to its shareholders (i.e. me) to price its products to get the highest return. If that means they are more expensive than the competition, then so be it. They are making profits from the Mac. I'm betting that Apple's finance department has their supply/demand curves in order and that the current pricing plan for Macs is close to what it should be. This is capitalism at its best.
