I think a more valid conversation to have is "why are so many trying to make apologies for the battery life of the apple watch?"
What I mean is, "about a day" is their official stance. Well, lets say it gets 16 hours with little use. Okay, that works for me. But, lets say with slightly heavy use it gets 10 hours.
Now that's not okay with me. It means I'd have to charge at work, or be left with a dead watch in the afternoon.
Simply put, Apple is not supposed to put form over function, Steve Jobs made certain that trends and public pressure was not to influence his design philosophy.
Tim Cook however is showing that he will run this company in a position of forced "catch-up" going forward. The increased screen size, the new apple watch, etc. none of these things play into their succesful mission statement that has gotten them to where they are today.
Instead, Apple is bowing to public pressure and putting form over function.
I refuse to make an apology for that.
