That it didn't come out sooner. 42 Sport, blue band and couldn't be freaking happier. The size, the crisp screen, the comfort, the ease of use, the seamless app integration and management via iPhone, it's all great! I truly don't have any complaints. It merely becomes an extension of you body and is personally tailored to do exactly what you want it to do and nothing else. The phone stays in the pocket longer, distractions seem fewer and everything is easier. I even went out to water the garden with the phone in the house and it stayed connected the entire time. This product is a win for apple and the future iterations of this watch will just get better and better. If you haven'g got your watch yet, you're in for a real treat. It IS worth it.
