I'll be the first to admit that I don't know all the in's and out's of economics. To me personally, it just makes more sense to sell more of a product with a lower profit than less of a product with a higher profit. Especially when the majority is strapped for cash.
For instance, lets say joe blow is online looking for a computer and is just looking for the cheapest. That could be Apple if they wanted to.
And if i'm way off on this, then by all means, please do school this young grasshopper.
