I still have a Late 2012 Mac Mini i7 and it runs great. Upgraded the RAM to 16GB and put in an SSD, runs like a dream. Would definitely look at upgrading if the newer ones were compelling enough.
Same here - I've been running a 2012 Mini as my media center since it came out. I actually purchased a 2014 Mini the day it came out, found out it couldn't be upgraded, and returned it the next day.
Yeah, the only thing i'm missing from my well beloved quad core mini is the ability to use a HiDPI display.
Are you developing for iOS 11 with it?
It handles everything I throw at it (Scala/Akka/Node, Docker, Discord, Slack, Million Chrome Tabs, ect etc etc)
I've been developing on my Mini 2012 for five years: native iOS and macOS, Unity3d, Xamarin.
