The problem is that, from what I heard, is that the 300,000 is a number made up of pre-orders and units they shipped to stores like Best Buy, but not necessarily sold.
So the actual number they sold to walk-ins is much lower.
300,000 is the number put into the hands of consumers on the first day of sales, VanDeKoik.
You make sound like pre-orders don’t count. Also because of production delays, they had to move delivery of a late batch of pre-orders to the 13th.
