Purchased, and arrived within 2 days. As stated, comes with El Capitan but in the process of downloading and installing Mojave, which it will happily take. For £600 you can't go wrong, and perfect for a Uni laptop. Thanks to OP.
Mine has arrived and now setting it up Manufacture date: May 2016, battery cycles 3, certainly never been set up. OS was El Capitan so bear in mind that High Sierra has been taken off the app store if you want to upgrade to that.
I'm currently using the Late 2010 model Air (actually manufactured Jan 2011 according to coconut battery) and it's had new thermal paste, a new battery from ifixit and a new charger, but otherwise still going strong - keyboard is brilliant. Hopefully I can get a few quid for it when I replace it with this one. I've got a nifty minidrive so will probably use that to expand the storage using a mini SDXC card.
LOL same here. Bit the bullet at £549. I can live with that, even if it's just to rip the OS off it for a Hackintosh and resell later on eBay at a small discount once it's not supported anymore. After so many of the recent screw ups from crApple regarding their broken butterfly switches, overheating issues and soldering or gluing everything to the motherboard -- I don't trust them not to screw up something major anymore. This Air is the least troublesome Mac to repair, especially with its removable PCIE SSD.
Well I've taken a chance on one of these from blackmoreIT with Friday's eBay discount code so it should come middle of this week. Will let you know.
