Odd that apple havnt listed IP rating or battery life, so hold out on the spec battle till thats confirmed.
If Apple aren't talking about the battery life it's because it's not impressive, or at least not impressive enough. As for the moto 360, I was so interested in this, but the SoC, wtf were they thinking, it's a slightly faster version of what's in my MOTOACTV running watch (which I bought 3 years ago) and was going into phones being released 4 years ago! It's a cortex A8 which has been superceded by the A7, specifically designed to be "a smaller, simpler, and more power-efficient successor to the Cortex-A8"
