Again, one thing that seems constantly lost in debating is that artificial scarcity does NOT imply that there was no demand for the product in the first place.
The Apple Watch might very well be more in demand than all the Android wear models combined, by far ( and it seems to be the case ), and Apple may still want to drive the desire for it to even more stratospheric heights by constraining availability a bit upon launch... Wich I believe have been the case for most iOs products they launched..
The fact that you believe that was the case for iOS products is a bit ridiculous. We're talking about numbers that are an engineering feat in themselves to have been met.
