If you do, get a good one. Like cables and other accessories, there are lousy ones out there. There are good and affordable options out there besides the ones from Samsung.

I guess it's easier to get hardware leaks (supply chains, etc.) than software leaks, which I assume are all done in house at Apple. I'm sure when the time comes, there will be plenty to discuss with iOS 11.
Otherwise, I completely agree with you. Apple has to catch up not only in hardware, but in many ways software, too.
There are iOS concept videos, btw.
