FYI, my sis, a software engineer for Hewlett-Packard for 35 years, bought her very first iMac after seeing mine, and playing with it for a few minutes last summer.
She says she will never go back to PCs, except to finish up a software package she is writing for a private client.
She loves the Mac, and doesn't like working on her PC any more. It did take her a couple of days to re-adjust, but she was having so much fun she didn't care.
