"Will it be different?" is the key question the regular people ask. They don't want there to be extra steps or new procedures. They sure as hell don't want the icons to look different or, God forbid, be moved to a new place.

These bright and capable people who will one day help you through knee replacement surgery all bought a Mac when they were college frehmen and then they never updated it.
