Wow, ya'll are a hostile bunch.
I found this forum, trying to figure out if it would be a good time to buy a MacBook or not after being fed up with PCs (I bought my brothers a Mini for Christmas), and talk about being overly sensitive.
(A) The idea that Mac doesn't drop its price to maximize profits for its shareholders is a great idea for Mac but bad idea for people who are looking to buy a computer. By that logic you justify selling the Apple IIE's for $1,500 since that would return even more value to Apple. The question is better phrased as, "Why should the consumer tolerate it?" Answers such as, "It protects your resale value by holding constant the retail price" is an answer that makes sense from the perspective of the consumer. But unless you're Steve Jobs or have otherwise large holdings of Apple stock, what the hey do you care if it makes Apple more money?
(B) The idea that someone would have to provide data (what kind? marketing surveys?) to support the idea that if Mac decreased their price, they would attract more consumers is a bit silly. Econ 101. But if you must... when I was looking into the Mini, one of the things reviewers/analysts raved about it was that it gave Mac a low/mid-priced foothold into the computer market allowing consumers who otherwise wouldn't have bought a Mac an entry point. Also, for data I can find quickly, in 2005 there were approx. 200MM PC units sold for revenue of 200bn meaning average sales price of about $1,000. Some of the market is above that; some is below. You hit the points below, you increase your market share. And Mac could stand to increase its market share.
(C) Ragging on the OP for the dialup comment was obviously childish since he obviously meant it tongue-in-cheek sarcastically. But the internet turns everyone into five-year olds, apparently. *sigh*
