I agree that 270,000 iPhones in 30 hours is an excellent opening, and well within the initial range/expectations that people were posting. It was the madness/hyperbole that followed over the rest of the weekend claiming up to a million sales that was ridiculous. Simple arithmetic of 1,800 AT&T stores and 160 Apple stores and how many iPhones they had to sell belies that.
Here in Sacramento, I counted ~200 waiting in line at the door opening. Within an hour and a half, they were all gone. This means to me that the Apple stores probably could, and did, sell 300 - 400 phones over that 30 hours. Best case, that means the Apple stores contributed ~64,000 iPhones to the initial rush. Now add in the AT&T stores. Most people were saying they averaged fewer than 50 iPhones per store, and when they sold out they had to wait until Monday for replacements. If that's the case, add in another 90,000. That brings us to ~150,000 iPhones for the initial rush. So, Apple pushing 270,000 to the stores is certainly believable. And, of course, some stores are vastly larger (and smaller) than others.
You can see how out of whack claims of 700,000 sales seems in retrospect.
No, what downed me in these numbers is not the initial rush. I think it was great and within initial expectations. What downed me was Jobs now asserting that he expects to push total sales to one million by the end of September. That averages out to ~250,000 per month. Not bad for Apple (~$135 million per month in new sales), but well short of previously announced expectations, and suggestive that internal Apple numbers indicate sales will not be taking off for awhile.
I hope this gives Apple the incentive to really dig into the identified bugs and gotchas, fix them, and then start adding some of the additional functionality that we're all clamoring for (like voice dialing, ring tones, and the like).
