However, the OS X Launchpad only comes into play when invoked.
And that has to do very little with the Start screen. The point was, OS X doesn't have a start button or start menu or anything. You'd have to use a "Finder" to launch stuff or pin it to the messy dock. OS X is really poor on this department compared to Windows 8 (and previous Windows)
