Didn't think about what? The battery is replaceable, so clearly they did think about it. Unless you mean make it user-serviceable? I doubt it has a traditional watch battery.
The (rechargeable) battery seems kind of obvious, but i meant, what about other parts (new bluetooth stds, more memory, faster cpu, new wifi... etc.)?
I think, or would assume, that a 10K watch has a bit longer lifespan then a few years? What when we reach iOS 10? Not backwards compatible? Thats already going on now, the iPhone 4 is not working with the Apple Watch. That was released less then 5 years ago. Now assume you have a 10K watch, or 5K... I don't think users are willing to keep buying watches (in that price range) every few years. Which makes me curious about Apple's Strategy...
I love watches, and im pretty sure i will get a (low-end) Apple Watch. But i find it hard to understand how the
high-end (Apple) watches can compete with the
true high-end Watches (Omega, Rolex, IWC, Breitling, Etc...)
Bottom line, if i would by a 10K watch i expect to use it for > 15 years. While a normal (mechanical) watch is subject to maintenance (which is $$$), maybe the inside of the Apple Watch is upgradable as well. The electronics inside don't seem to be the most expensive part, while a golden case is...
