I'm gonna share this experience: My dad is a long time Windows user, but he really liked the iMac G4 I had in my room. So, one day I gave it to him. He is an accountant, so I installed Office 2008 and put the Office icons in the desktop. Time he had troubles adapting to OSX? 30 minutes!! He told me the OS felt so modern, fast and slick! Not bad for Tiger OS He doesn't like iTunes, but who does it?
