Your assessment makes absolutely NO sense at all. Phones are all about the UI....sooo, if you take away the Android GUI, what are you left with? Ah, right, the same as if you took away the Apple GUI.
You clearly don't know much about Apple's OSes, or mobile OSes in general.
They are all 'Nix based, thus essentially making them VERY alike. Apple's GUI is different, just like using a different Window Manager in Linux, if your familiar.
At the risk of sounding fanboi-ish, Apple's GUI is the REASON it's such a great UI for individual users that make have trouble with less-intuitive interfaces. It's also nice to just have an App called MAIL, and not Outlook, or "Messaging". Just call it what it is!
Yes, it's "closed" but how many people in corporate environments are switching things around every day with users' phones? Not many. You give them what they need, and that's it.
