It will not happen, as it has been with Mac OS since its inception and when it still was titled System instead of Mac OS.
It also adheres to Apple's intention to simplify things.
In
1984 it looked like this:
That's all good and well, but if you apply the same logic, it means it will be there for as long as the OS is, which I don't think will happen... everyones touting 10.7 to have multitouch, so the menubar presumably wouldn't work with that model? Also I thought Apple was a company that looked into the future, presumably a nearly 30 year old UI is not the most practical in the moden age.
Menu Bar is VERY nice with Photoshop for example. There are hundreds of different things that can't be used without something similar to Menu Bar.
It may well be, but, with Windows, it's just appears at the top, not taking up any extra room, just a slightly different implementation, however if you look at Google Chrome, the Menu Bar doesn't need to be there, the top bit is self contained... and on a 13" screen, every pixel is valuable - even IE9 lets the page shine through, with OS X you have the menu bar, and the dock (yes, I know you can send to back, but then it isn't as easily accessible as it always seems to hang before it shows), which is probably double what the taskbar in Windows is ...
And anyway, it has to be said, that digging around a menu, I don't think, is actually all that simple, whereas icons etc are much better, especially in something like mail, where things life Font are in a completely separate windows, when it could just be a drop down box in the actual top bar (the white plastic theme bit, I think it's called), which at the best of times, is taller than it needs to be, and empty (and yes, I know it can be minimised, but then it's even more clicks before you can do anything productive), anyway just my opinion...
Chrome and MS Office are non-Apple apps that have elected not to follow the Mac methodology. Apple isn't going to adapt Mac OS X to 3rd party app developers. It's up to them to adapt to Mac OS X, if they choose.
I'm very much aware of that, as I pointed out in the original post, but I was using them as references, and with Chrome, you can't exactly get much cleaner, can you?
