I'm ex-Windows user. There was no way to drag maximized window, but it's possible in OS X (I have Mavericks).
There is full screen mode, but I have found one annoying thing there - it's too hard to get access to the Dock. I have to point my cursor at the bottom of the screen and wait for a long time, unlike default behavior in non-fullscreen mode.
Is there a way to lock maximized windows, allowing to move them only with ⌘ or ⌥ key?
