I've been around here forever and rarely need advice on purchases, but this one has me stumped. Quick background: My parents are in their mid 60's. They are VERY computer illiterate. I gave them an ancient (core duo I believe) Mac Mini like 6 years ago. It's still working to this day, which amazes me. Their 10.5 uptime probably measures in years... (I updated it from 10.3 I think years ago). I am going to visit them in a month or so and want to replace their aging rig with an iMac. I bought them a webcam for their Mac Mini and they used it once, then it "broke." Fact is, they don't know what to do with it since it's not integrated. Plus, when their keyboard/mouse batteries die, they call me saying they have a "virus." So, that's the baseline I'm working with. They are lucky to get on the web without issues, so they are very computer illiterate. That said, what's the most reliable iMac out there in my price range (up to $400 or so)? I don't want a machine that has graphic card issues or other such "gotchyas." Just something I can put a clean install of (Mountain Lion?) on and call it a day without expecting frantic calls saying things are broken. I'm out West and they live on the Gulf Coast so its not exactly easy to drive over and bail them out. If something goes wrong and I can't remote in to fix, they give up and I get frustrated because I can't be there to help. Thanks in advance for any advice. I'm fully aware of eBay and Craigslist, just looking for the best model out there (either white iMac or aluminum, depending on price) that I can set up and not worry about for another 6-8 years.
