My parents are using a 2008 Acer Desktop PC and I'd love to get them set up with an iMac. My wife has a Late 2012 21.5-inch iMac that she's selling, as she's recently picked up a MacBook for college use. My initial plan was to pick my parents up a Late 2017 iMac, either the entry level model or the 4k model, next time they go on sale. But now I'm wondering if maybe this Late 2012 model would work just as well for their basic needs (Internet, E-Mail, Photos, etc.) and maybe I can just "buy it" off of my wife instead. Here's a comparison between the three models in question on EveryMac.com. (The Late 2012, and two Mid-2017 models I'm considering.) Any thoughts? Would it be best for me to just pick up a 2017 iMac for them or would the 2012 be sufficient? Thanks for your help.
