My mother (who isn't a computer buff) bought an iMac recently when I recommended she get one to replace her outdated PC. She loves it except she has a hard time understanding a lot of stuff that she can handle in Windows at work. For instance, while she uses "Windows explorer" to organize stuff on her hard drive in Windows she has no clue how to do that on her Mac. I believe she needs a good, easy to understand (as little computer jargon as possible) and basic "switching" guide with plenty of illustrations so she can get a little more in control of things. Any recommendations? She's using MacOS 10.5.4 on an iMac.
