I really enjoyed both OS X and iOS 8's new feature set.
Apple gave everyone what they wanted plus some.
We now have quick reply, a file system, better keyboards, safari extensions, and widgets all introduced in one version of iOS.
The continuity stuff in Mac was awesome as well.
As a side note, I can see that Apple has really paved the way for future wearable devices that take advantage of continuity and Apple's other developer features released today.
