Hi all, Has anyone upgraded from the iPad Air 1 to the new iPad Pro 10.5"? If so, would you say that it was worth it? Is the boost in performance considerably noticeable? I ask as I notice that my iPad Air 1 seems to lag and behave in quite an 'un-Apple' like way in terms of performance. It is quite disappointing given that I've only had the tablet for 3 years and since updating to iOS 10, the iPad's performance became quite slow and juddery. In addition, background apps regularly re-load and will not retain specific pages. Any advice would be greatly appreciated as the iPad Pro is expensive, but I would be willing to upgrade if it is a solid and somewhat future-proof option. Many thanks.
