Thanks for all the replies, its been an interested read.
I can certainly appreciate that a piece of technology is never going to be future proof but since I upgrade every 3-4 years I'd like to see it last me that long. Perhaps in the future I should be more apprehensive updating to the latest IOS version.
I'm going to take the plunge and hopefully in 3 years time the ipad pro will still run the latest IOS to a useable standard.
