I think you mean: Apple Watch is A solution for those who already own one and who are wearing it. Surely you're not suggesting an AirPod buyer also buy a $300+ wrist-based volume control device, right?Apple Watch is your solution there.
Getting back to reality, the AirPods really do need inline volume/track controls without Siri. I'm still going to buy them and I'll be annoyed when I have to pull out my phone (or reach for it, since it's not always on me while listening to Bluetooth audio), but the convenience of truly wireless earbuds combined with very easy charging and pairing and exceptional battery life, I'm going to love them. We'd only be a software update away from a nearly perfect product for me.
