I don't think you have to worry about feature differences until at least iOS 9.
I've been wondering that same thing but haven't been able to find anything on Apple.com or through googling about it.
I don't know about that. Siri was a 4s-only feature of iOS 5. And I have a funny feeling the 240fps video mode on the 6 won't be available to the 5s - but I'd love to be proven wrong there.
Hardware specific features like Apple Pay, which requires the new NFC hardware built into the 6, obviously won't work on older phones - just like Touch ID on the 5s was specific to that device. But when it comes to all the software features of iOS 8 I would love to know what the rest of us do and do not get to enjoy![]()
On the 6 and 6+ you see contact photos in the Messages app, I believe. Do not have that for the 5.
the 240fps video mode is exclusive to 6 and 6 Plus.

It doesn't list the time lapse option mentioned in the keynote, so I'm hoping that's tied into burst mode, which is listed as being the same across the 6/+ and 5s.
6+ has landscape homescreen and additional buttons on keyboard when in landscape.
So no home screen landscape mode on the 5S? Link?
