I'm committed to the Mac approach, with the addition of using LogMein for remote access and control. My father, now in his 80s, has used Macs that I have given him or bought with my siblings going back to System 7 days. He's on OS X now with a Mac mini. There is always some little thing that troubles him and I've found that by having LogMeIn running all the time allows me to connect to him from my OS X system and talk him through the solution or correct toolbar problems he has in Excel (the old PowerPC version) easily and quickly. No viruses, no antivirus software, few hardware issues in any of the five Macs he's had over the years. Usually it just works.
