A few journalist were talking about this on a podcast the other day. Studies have shown that this method results in the best customer satisfaction overall, free advertising, and doesn't hurt the bottom line that much.. within the practical constraints. It may also eliminate most of the "scalping" type feeding frenzy. The only thing else that may work is to have a sliding scale price, day 1 price is $1000, day 2 is $900, day 3 is $800, etc. Although that will be the best for the bottom line, no one is going to do that (except maybe Samsung), as they think it will hurt customer satisfaction.
So Apple is doing the right thing for you and other consumers....
