It is THE sneakiest way to sell more watches - and finally make a lot of people ditch their old watches, they gave to their parents/children, because they were still "good enough" - now they lack the most interesting new feature.
Good move - yet - no Tim, it is a bit too obvious....
Why does every single change/innovation has to come with someone sneering that it is greed motivated?
What would you have them do, never change?
This is great for families... and if Apple sells more watches... good for them!
