I agree that Windows and OS X are roughly equal (maybe OS X is a little better) when it comes to UI consistency, consistent keyboard shortcuts, etc. That's not true of Linux applications, generally (which is why I said "X-based Linux applications," not "OS X applications").

As far as your second point, I'm glad for you, but it wasn't my experience and I got really sick of jumping through hoops trying to emulate a Windows environment for various software that was not available in OS X.
