Still on my first 13" 2012, i5 cpu, 4 gb mem, 128 gb ssd model. The battery is shot, but otherwise it took a beating and is still running like a champ.
Hopefully next year they will still be selling these puppies. Because I can not find something with similar price, spec and build quality. Air is really one of your best priced ultrabooks.
Otherwise I recommend you don't settle for a i3, you are going to regret it. Had to give my brother-in-law advice on buying a notebook for writing docs and surfing, etc. Said a i3 should be fine for his needs... did I regret that at our next "free technical support session" :/ get a i5 atleast!

Also, macOS is a Unix[0]. gnu/linux is the 'nix like os around here ;)
