That’s essentially where I am at too.
As I said, I planned on getting this day one. It’s been four years since I got my launch day Air 2, for me it’s time. Except I played with the new Pros and keyboard folios and I was just not impressed, particularly with the new higher prices. What was $900 last year all in with a 64gb WiFi model, pencil, and keyboard is now $1,100. And with some features/accessories removed.
It pisses all over the iPad Air 2 and is much better than the 10.5. Sounds like you can not afford one so just buy the basic 2017 model, it too works with the first gen pencil and is faster than your air 2.
