I use my iPad Pro 2017 every day, my mother is using my old IPad Air 2 but she wants a bigger screen and the battery on the Air 2 is degrading (which is for enough considering how old it is). I had an issue with the original 2017 iPad Pro I brought and after sending an email to Phil Schiller about the service I was receiving (i was quoted £544.66 out of warranty), I got sent a brand new 2017 iPad Pro after talking with Apple Executive relations and sending my dead iPad back to them.
Anyway the dilemma I have is do I give this new 2017 iPad Pro to my mother and buy the new 2018 iPad Pro? after looking up the serial number I found that the new iPad they sent me was mace early 2018 in China, newer than my original 2017 iPad Pro that I brought on August 19th 2017. I really like the look of the new iPad Pro and Apple Pencil 2, but will Apple be updating the iPad Pro at some point this year.
I think based on past history, the iPPs get updated appx. every 18 months. The 2017 iPads came out early in the year (if I remember correctly), then the 2018s in the late fall. I think the 10.5 was released at a different time - I’m sure someone who knows more than me could correct my mistakes.
It makes sense for there to be different manufacture dates though, since they would be constantly making more iPads, even of the same generation, until new ones were released. I’m sure if you bought a 2018 at this point, you could potentially get one manufactured in early 2019 - it’s still the same iPad design though.
Obviously no one can tell you which way to go, and there are always pros and cons to both sides, but I’ve been happy with my purchase, and I know many others have as well.
