I’m not sure if OP is reading us at this point, but he said he has an Air 3, so he can wait and use such awesome machine until the iPad Pro with mini LED is released at the end of 2020. And that’s my advice at this point for anyone else with a fast iPad, even if it’s a 2018 iPad, just wait if you want an iPad Pro because the next one is gonna be better, will have more RAM, and just for that it is worth the wait. Also, there are rumors about a back-light Keyboard, even some bizarre rumors about a keyboard with a trackpad. Who knows, but after year and a half with the same iPad Pro, I’d wait.
I decided to purchase this 11” iPad Pro in October, First, because I wanted to take advantage of the Back To School promo, and the returning period allowed me to return it if there was an October event. There wasn’t October event, so I kept the iPad Pro and the Beats Solo 3. Secondly, I couldn’t wait more because my 2010 MacBook Pro was old and the battery didn’t hold all day.
If it was now, I’d probably wait. However the 2018 is still an awesome machine, super fast and super light (and super gorgeous).
