Sadly, as an Apple fan, and collector, I am underwhelmed with both newest models, especially considering their prices. I was waiting out to see if the new models had any new physical features (knowing it was unlikely), but sadly they actually deleted one, the mute/rotation lock switch, which he makes little sense to me (how many pennies per unit are they saving)
Just need to decide now if it is worth it for me to save ~$300 to abandon iOS and go with an Android tablet that has some of the hardware features I am after. The downside is, it will also require me to purchase Android versions of the photo / video tools I use for editing and posting content, and find ways to share data between my iPhone and tablet when traveling without a laptop. I know of a few options for this, however iCloud has been my tool for most of these situations.
Using my old iPad with iOS 8.1 will be the deciding factor. Continuity may keep the newest iPad Air in the running for me.
