“Apple is not saying how many pre-sales they have actually received, but it is far more than 2.3 million.”
That would be ~0.5% of 450M.
You don't seem to be paying attention. That half of a percent of the potential was pre-sold in the first ten minutes . . . And Apple has been selling Watches at a steady rapid pace for TEN days since those ten minutes of sales. Your point means nothing if you intend to claim the sales somehow are minuscule compared to the potential. We don't know how many or what the actual ten day percentage is except that it is far above the number Apple expected. . . Hugely above.
