Moving from Windows to OS X? The Unofficial Apple Website points out OSXhelp “Insanely Simple tutorials for the first time Macintosh user.” According to TUAW, the site should be of great help in explaining all those little things experienced users take for granted. A visit to the site confirms that it shows some promise, including this handy primer on keyboard shortcuts…. A topic always of interest to myself.
Other sites that help grease the switch: 
Apple’s own official Findouthow
and the cleverly titled mackindergarten.
I recently made the switch from a PC to an Apple and purchased a mac-mini. I am a solo practitioner and I am semi-computer illiterate. I am open to suggestions for making the transition, not only easy, but profitable. Thank you.
