You have it backwards. Except for the very first iphone, largely Apple steals from UX, technologies, and form from the Android ecosystem. Apple is great at polishing ideas, but not so great at launching new ones entirely. They do have a few, but not many. Most of their "advances" can be traced back to non-Apple ecosystems. Apple has a closed ecosystem that they control completely, which I why I (and many Android users) hate. They stand on the shoulders of open systems like Android and watch for innovation that has merit, pluck it out, polish, and deliver it as their own, then gain the bulk of the reward. I see them as largely parasitic. Hell, they even claim reliability claims for OS X while standing on the back of unix.
