I'm on a 2012 11" MBA with 1,800 cycles it is perfectly fine as the day i picked it up but i think i will pick one of the newer ones that launched today. Not sure which one,we'll see. But yep, i'm thinking about upgrading. Have been waiting this time since about 2 years ago but still we'll think about it as this machine works perfectly fine and meets my needs, upgrading would be just spoiling myself for the sake of it.
