I think the area Apple focused on the most with iOS 8 was continuity with other iOS devices and OS X and the developer APIs. Continuity will be great if you have another iDevice or a Mac. Although from a non-developer point of view I can see why people might feel somewhat disappointed.
As a developer the amount of new APIs now available means we can add features to apps we haven't been able to before, the new Swift language is also a lot nicer to use IMO, so from a developer point of view its a huge step in the right direction, and for the consumer I think you'll start to see a lot of new possibilities when developers update their apps to take advantage of iOS 8.
