I'm trying to convince my nephew to let me buy him a ~2012 pre-owned loaded up Mac Pro for ~$800 from a reputable re-re-seller, as its performance should be more than adequate for his entire 4 years of bio-med. 2012 2.5 MHz i5 MBP, 8 gig ram, 500g HD, +2 year warranty, excellent like-new condition, ~$800 with el capitan OS 10.10. Plus it has a disk drive and actual dedicated ports! (network, USB-B, SD, magsafe, and maybe even thunderbolt). No dongle madness! I'm facing resistance from his parents (sister & brother-in-law) about "isn't that too old?" Isn't there a site or iOS app that lets you compare stats/performance of various iterations of macs? Unless he were going into heavy music/video production, I can't see this being a risk. Secondly, any thoughts out there about the pros/cons of my outlook on this suggestion? I.e., the likelihood of this being a robust/solid option for the next 4 years of use? Much appreciated, THX.
