I understand your point, but I don't completely agree. I'm not a done deal. If they don't get me the 6+ before the Note 4 is available I would be tempted to switch. I was on the fence on which one to buy anyways and watching people walk out of the store with a phone I preordered 1.5 months ago is enough to make me jump ship. They should take care of the people that paid them first or don't even have a "pre-order" option. Only looking at numbers makes business sense on paper, but there is something to be said for honoring current customers instead of treating them like a done deal.
The 6 plus SG 128gb I ordered on 9-16 is going to be my first iphone. But if I don't get it by the time the note 4 is available then I guess I'm getting the note 4 and staying with android.
