So my parents are currently using a PC that I built around 2003. It still surprisingly runs GREAT, especially since they don't use it for anything demanding. The problem is, they suck at keeping spyware off of it and I believe there's an issue developing with the hard drive. They've only used Windows but are still pretty noobish at using computers, plus there isn't a steep learning curve for OSX. I'm thinking the best solution for them is to get a Mac Mini. They don't need anything powerful, and they aren't too expensive. Best of all, it won't be infected with spyware. I've never had an issue with spyware on my PC, but honestly I have no clue what they're doing with theirs. So my question is, how is the Mac Mini in terms of general performance and reliability? Is the cheapest one worth it? I'd build them a new PC for less money but I think they'd like using OSX and spyware will not be a concern.
