I have a chance to get one of two MBAs. The first is a 2015 2.2 GHz i7, 8 GB RAM, 512 GB SSD, with box, etc. It is $500, and comes a with a spare 85 watt Magsafe adapter, wireless (Magic) keyboard, trackpad, and mouse. The second is a new refurb 2018 with 16 GB/512 GB. Military price is $1223. Will be used for typical home stuff; nothing dramatic. Thoughts appreciated.
