Are you suggesting that the current feel of the OS is not up to standard?
In Mac OS X, the "feeling" of Safari to me is much better than Chrome, Firefox and Opera. I'm not sure what exactly gives it that unique feeling, but to me it just feels "right". The responsiveness of buttons, the appearance of control elements. I just prefer Safari over other browsers in that respect. So I understand that feeling is important in an OS, but back to your comment, are you waiting for an OS that feels right/better?
I do love iOS, obviously, if not I wouldn't have an iPhone in the first place.
I do, however, find Apple's hardware far more beautiful, and that's Jonny's work. And if he does a great job at that, it's likely that he'll make aspects of the software look just as beautiful.
I don't know, it's probably just a personal thing, but I find myself contemplating and enjoying the look/feel of the actual iPhone quite a lot more than I do with the software.
