Huh? Apple offers 1366x768 in 11", 1440x900 in 13", and 1680x1050 in 15". The only comparable-and-better that I know of is the 1600x900 HP something-or-other.
They aren't standouts (although the 15" at 1680x1050 is really nice), but they're no worse than anybody else.
EDIT: I misread the original post. Sorry about that. That said, OS X isn't appreciably worse as far as resolution independence than the rest of your options. (Not that that's praise for OS X, but neither GNOME nor Windows are particularly good either.)
