Good question. The rumored iPad Pro (big-screen iPad) is also supposed to have Force Touch. So if the stylus is only compatible with that, it may not work -- or not work as well -- on the Air 2.
There are rumors that Apple is working on VR projects, and I would definitely expect that in the future. But highly unlikely for today.
I think the split screen and picture in picture video they showed off in June is a good start. Will be interesting to see if addi'l features are shown today.
I'm sure that's true for many folks who already have last year's iPhone 6 and 6 Plus. But there are a large number of people coming off an iPhone 5 or 5S contract who just want a new big-screen phone, and the 6S/6S Plus will be the latest and greatest.
Great question. Apple has been good about cannibalizing itself (instead of letting others steal their business), so the iPad Pro "eating" Mac sales would fit into that tradition.
Ok, now we've got three polls running -- we really care what you all think!!!
