I had a MacBook Pro 13” since 2011 and always wanted an Air but didn’t get one as I could only afford one and wanted something more versatile. A few months ago I excitedly upgraded to the 14” M1 Pro which is incredible and I love it. But I still wanted something light and that would not cause me anxiety about it being stolen or damaged (it cost $4500 including Apple care where I’m from) so I got a second hand Air 11” 2015. It’s only 4GB of RAM and the F11 key doesn’t work but besides that it’s cosmetically in like new condition. I’ve been running all my word processing documents on Mojave and even installed Windows via boot camp which I’m using for light games and statistical software. It’s perfect with MagSafe, 2 USB ports and a thunderbolt/mini port. Really loving having two MacBooks: one for portability/bootcamp and the other for more intensive work.
