The hard work of syncing kill me. I have to switch from these kind of paper device as it is hard to manage info across them. Pad like devices are paper to me and kindle. It is more like in Star Trek you see captain use a few pad devices as if there were separate books/doc. It would be better if the two New iPad Air can manage the files in their app. As it can’t, I bought new old stock of macbook 12”. It is all portable and all work together. as background I own kindle, boss the pad size and the huge one (max 2). Once the ipad has the paper like screen protector i did the switch. The newly bought 15” i9! Is not portable. Hence the macbook 12
