You and me both brother. Some things I just don't get in OS X. Like the "zoom" button's inconsistent functionality. Hilarious that OS X Lion is going to change this button to go literally fullscreen now (without toolbars, desktop, etc) which might be pretty annoying too but I guess we'll see.
I agree about the maximize button - after a decade of arguing for the current implementation of it (rather than the make this window fullscreen version that Windows uses) they're now finally switching it (and, of course, talking about how fantastic it is).
Rumor has it they're finally making windows resizable from any corner, too.
Of course, I shouldn't be shocked any more since Apple (and Jobs specifically) constantly play that game. I love OS X with a passion, but I can't help but chuckle at this point when they do it.
i like the zoom to max size for content much more than zoom to whole screen but i'm someone who never uses it anyway. i have divvy which makes my life a little more manageable.
