I see what your saying. Basically apple took the iPod touch interface and added a phone to it. So it's pretty much made to be an mp3 player in a sense and just kinda grew into what it is today.
Sort of. iOS was built with the phone stuff as a secondary priority. First priorities were the browsing, media, and applications. So it's really great at those, but is limited at the same time. It's just a very different UX concept than what android is. I have a strong feeling a significant revamp is in the works for iOS since it hasn't changed much visually since 2007. It's still a very powerful os, but it's not making as much use of that power as it should.
