It's not an exact science though. This web order sequence of course includes all Apple products sold through the US Online Store. But for today, this is relatively insignificant when compared to the iPad orders. The average daily order volume from January 16 to March 5 was about 16 thousand orders per day. From March 5 until the first order submitted after the store opened today it was about 14.5 thousand per day.
But today, that's a drop in the iPad bucket. The other products would account for 600 orders per hour, assuming the base rate continues the same. Yet for the first 6 hours since the store opened, we've seen the sequence increase by more than 88 thousand orders in total. That's the baseline daily volume, per hour! For the last 2 or 3 hours the rate has moderated to about 7 thousand per hour, from more than a thousand per minute in the first 15-20 minutes.
I'll keep an eye on this rate and the estimated total over the next few weeks.
Thanks for everyone's submissions,
