Let the hive mind of Engadget get that for you.
"I am trying to configure out a really dumbed down and intuitive PC for my grandmother. She recently had a stroke and while she is under my care I would like to repurpose a laptop for her to surf and email her children. Anyone have any experience with what input devices and UI's are really understandable for the over 80 crowd?"
Thanks for being a voice of some kind of logical reason against this "I-hate-macs-cuz-they-expensive-stupid-non-mainstream" reasoning. If they think you're intolerant, they need to look at themselves honestly.
