The difference is, with a new product like this, sales should be picking up. Early adopters pick them up first, and evangelize to the masses who either through word of mouth, or direct demonstration decide they want one for themselves. Then, over time, after it's reached it's peak, or close to, you see upgrade numbers each year, like you described. Only what's happened here is different. There was an initial surge among early adopters, but the masses didn't follow. This isn't a "have to have" product. People aren't realizing that this fits into their lives like their phone did. Need I remind you also, that people around here were literally talking about how this was going to completely replace our phones - hah. No.
I'm sure this has been posted but not reading 27 pages.
Nothing but a click bait story. Apple sold 10 million iPhone 6 when it was introduced in one weekend or 3.3 million phones per day. During earnings call, APpl eannounced it sold 74.5 million phones or 828,000 per day. OH MY GOD, IPHONE SALES TANKED 75%!!!!1!!!
