It seems like a small upgrade from iOS 7, not as big as from iOS 6 to iOS 7, though. I particularly like the updates for family use, they seem to be really great.
As I expected, they cut out the iPhone 4, so you need a iPhone 4S or higher or a iPod touch 4 or higher or a iPad 2 or higher to be able to upgrade your iDevice to this version.
What do you guys think of it, does anything pop out to you? I don't really see anything in particular that awes me as it has in the past, but maybe they're just saving all their energy on the new iPhone? Guess we'll know in the next couple of weeks!
