You don't seem to understand the basic principle of volume. Sometimes, the best way to maximize profits is to lower prices and increase in sales volume.
Right, that's the model that Dell tried. How'd that end up for them?
Have you followed Apple's quarterly statements recently?

Mac Sales Volume:
Q1 2011 = 23 percent unit increase over the year-ago quarter
Q4 2010 = 27 percent unit increase over the year-ago quarter
Q3 2010 = 33 percent unit increase over the year-ago quarter
Q2 2010 = 33 percent unit increase over the year-ago quarter
Q1 2010 = 33 percent unit increase over the year-ago quarter
The Mac's sales volume, at current prices, is already growing significantly. Add much more on and it becomes a unmanageable mess, IMO. Think it's already hard to get a Genius Bar appointment now?
IMO, Apple does as well as it does because it does things differently .. it gives a different experience, especially with its stores. With the volume increase that you're proposing, they become just another mass merchandise retailer. Essentially, they lose the specialness of their brand that they've spent the last 10+ years making.
They're already realizing an incredible profit. Short-term, yes, they could increase that. But I don't think they can do that (via mega-Mac sales volume) and keep the brand loyalty that makes them what they are.
