The high price provides room for heavy discounting once the initial demand subsides.
It's all about matching supply to demand. Apple has priced past phones too low at launch leading to long lines at stores, long waits once initial stock sells out, scalpers worsening the situation whilst pocketing handsome profits at the expense of Apple's regular customers.
Wait a few months and you'll get $200-250 off at resellers (but not at the Apple Store, obviously). A few more months and it'll be $300 off.
Patience.
Where? Where has this ever happened? The only time I have seen a great discount was at a provider and only if I traded in a smart phone that was 2 years or less in age. You will never see these discounts at APPLE, NEVER. As for Walmart, BestBuy, etc, there is always a catch. So, your really not getting it for that much off. As for "Patience" as you put it, here we sit, 4 or so months from the announcement of the next installment of the iPhone, yet, the prices are exactly the same, EVERYWHERE you look for the 7/7+. The only deals you can get is Buy 1 Get 1...(they will give you 24 equal payments back to you until the phone is paid off).
Also, you actually believe the 7+ and all previous iPhones were priced too low? What are you smoking, please share it with everyone else. The reason Apple has long lines is because of all the HYPE & more importantly, they never have enough iPhones, plain and simple.
