Hopefully "Real OSX" means that you won't run into most of the same problems porting from OSX to the Apple phone than you would porting from Windows to the versions of Windows for smart phones. Example: I just talked to a guy (someone not within Microsoft, this was outside of MS) who said that the compact Windows versions they use for smart phones don't support any right-to-left languages at all. They had to use a third party tool to to get Arabic to work.
