The totally funny thing is that if Apple had raised the price by $50 or $100 due to the popularity of the iPhone, all of you early adopters would have been braggin' your asses off about how smart you were to stand in line.
I don't understand your logic that you were abused by the price cut, because you weighed the total value of the iPhone before you paid for it, and willingly plopped down your $600. But you knew (or should have) that Cingular could have reduced service in your area the very next day, leaving you with nothing. Or a fatal flaw in Apple's marketing plan might have caused the phones to become extinct in less than a year (leaving you with a $600 iPod Touch+).
But the iPhone you bought is still yours, you're still getting to use it. It's not like they changed carriers, and now your phone doesn't work. So, better luck next time. After all, it's 200 bucks. If that's a really big deal to you, maybe you shouldn't be out buying a $600 cell phone. (Gee, if you had bought $600 of APPL stock instead of an iPhone that day, you wouldn't be crying about the price cut today, would you?)
I don't understand the surprise at the rapid price change, either. These people must either walk everywhere you go or completely rely on public transportation. People who drive cars and buy fuel face these kinds of price swings every day. I don't know how many times I've seen gas fluctuate by 12% - 20% OVERNIGHT (usually right after I fill up only to see it 25% cheaper at the next exit). I can easily lose $200 in two months by not watching and timing where and when I buy gas. It's all speculation.
Another example: I buy CoffeeMate(R) creamer regularly. The small grocery store down the street from my office charges me $2.75 for a bottle, but the big one closer to home always has it for $2.35. But frequently another store has it at 3 jugs for $5 at the same time I'm paying $2.75 apiece just for proximity convenience.
I guess I should write hate letters, and try to convince people to boycott the small store. Or maybe I could just learn to do without creamer & drink coffee black while I wait for CoffeeMate to go on sale. Ask your girlfriend... timing is everything. (She's the one who likely pays $200 to get her hair done, even though she knows it's gonna grow out in a month.)
