everything is just as random as on WIN-DOS.
Erm... dude... DOS died like, so many years ago. In fact, there are people who were born after DOS died that are old enough to hold drivers' licenses in some nations.
As for inconsistent UI - remember that they're trying to redraw everything here in shiny Ive-o-Vision; there will be a lot of UI gaffes. But that's the same with every version of the OS that's made GUI changes. Look at the terrible mismatch in Tiger, for example, of pinstriped, plain, and metallic windows. Or the constant changing and misalignment of pretty much all window elements in iTunes.

To the OP, I'm glad you got that sorted. I have the eternal headache of "This iPhone is synced to another iTunes Library" every time I plug it in.
