That said, this is a beautiful piece of design. I think they've outdone themselves with this one, it's a truly wonderful device. Unfortunately, I have a horrible feeling that it will only be a matter of time before we see the usual Samsung vs. Apple patent violation claims being thrown around again (despite any possible prior art etc.).
Personally, I still think the tech isn't quite compact enough yet, but we're only one or two generations away from a slim-line, waterproof, and functionally integrated piece of kit that will actually complement the existing tech. The integration with dive computers / cycling computers / sports cameras / personal drones :-) etc. could be incredible!
Hopefully Apple's entry onto the smart-watch scene doesn't end up mired in too many patent battles... I'd like to see these devices progress as fast as possible!
Bravo Apple design team!
