I completely agree - I don't want Maximize like Windows.
There are lots of things I don't
want in OS X and Windows, but that shouldn't dictate what others can or can't have. What harm would a tiny Maximize button next to the tiny 'traffic lights' buttons do? Would it steal space? Would it make you cry?
A window should take only the space it needs to display its contents.
No, a window should take up whatever space the user wants it to take up. It's called freedom of choice. We don't need some communist system that dictates window size for us like OS X does, with its lack of a Maximize button and resistance to window resizing.
It seems to me maximize on Windows was done so that people that were used to one program at a time in DOS would feel comfortable.
No, it was done to reduce desktop clutter so that you don't have to look at your desktop icons, your desktop wallpaper and bits and pieces of other applications while you're focusing on your work. That sort of clutter was inevitable on Mac until Apple introduced Spaces to cover their arses. Microsoft tried the Mac paradigm in Office, eliminating the main program window and putting all documents in separate windows floating around, but users hated it with a passion so M$ quickly moved back to the traditional window structure in the following version.
Also, since there is only one menu bar in the Mac
Yes, and that's one of the main reasons why some people puke all over Mac and would never switch to one. The single menu bar is a retarded solution which dates back to an age when desktop real estate was in short supply.
Apple wanted to ditch the single-menu solution and give OS X a fresh start, but narrow-minded Mac luddites started bawling their little eyes out so the menu had to stay. So now we're stuck with this neanderthal solution that makes working with a dual screen setup a PITA, because whatever application you place on the secondary screen will have its menu on the primary screen. If these are two 30" screens, it won't stop at carpal tunnel syndrome, your arm will fall off from making the mouse cursor travel 6 miles roundtrip every time you want to access a menu item.
Text menus are an outdated solution anyway. Microsoft started eliminating them (or at least hiding them) in IE, WMP, Office 2007 and other applications. Apple did the same in Safari 4 for Windows, which is actually better than Safari 4 on my Macs...
Also, the menu bar in OS X is a total waste of screen space. The middle part is always empty because no app has that many menus. Here's an example where Windows is much more efficient - it fits both the menus and the min/max/close buttons into the same space where OS X only has the traffic lights buttons, and thus needs a separate menu bar in addition to that.
Man, the OS X menu font is heee-uge when you see them side-by-side like that, looks like some sort of accessibility mode for the visually impaired...
