I got an iPad Air 2 (128GB) Wi-Fi Only Space Gray today (Wed, Oct 22nd) at the Apple Store at Polaris Fashion Mall in Columbus, OH USA. They didn't have them on display yet, but they did have them in stock and you could do an in store pickup. When I was at the store I bought one. I hung around the Apple store for a few hours and I saw a couple of people buy the iPad Air 2 but there wasn't much demand for them. From what I understand they will have display models tomorrow (Thurs, Oct 23rd). I doubt it will be difficult at all to go to an Apple store and get your hands on one.
