I think you have a valid point there. Cell phone sales have been pretty much flat for some time now because the market is saturated. Basically anyone who wants/needs one already has one and the only sales are for replacements of existing models, but the market demands ever increasing sales or a company isn't considered "successful". That means they have to keep coming up with new ways to sell us stuff we don't really need. But that being said, I think there is a good reason for something like the Apple watch's health monitoring. The fall detection system could be very helpful for frail elderly people, and the ECG function the new Apple watch could be useful for someone like me who has heart rhythm issues. But the ECG technology is still new and how well it works in the real world hasn't really been proven yet. And that sucker costs $400+ depending on the model and features.
