How many buyers have actually got their hands on an Apple Watch at this point? The launch weekend saw only 22% of U.S. buyers get a delivery from Cupertino. Or 376,000 out of a total of 1.7 million early U.S. orders.A further 647,000 Apple Watches, or 38% of orders, have yet to be assigned a shipping estimate.Some 547,000 watches will ship between April 27 and June 11, with 33% slated to get their device in April, and 28% in May.

So a lot of enthusiastic iPhone users are patiently waiting for their Apple Watch to arrive. Including me.
