I’m posting this from a 2013 MacBook Air. It’s not even breathing heavy.
Love those pre- Retina models. Not gimped with 2 USB-C poets, still light, etc.
All I ever used it for was browsing and light-duty data entry.
And for some reason, my eyes just don’t get the Retina vs. non-Retina differentiation for a screen that size. iMac it makes a difference. but Air, iPads, etc? Not really.
Plus older Airs has MagSafe. Good stuff. Miss them.
