External 4K UHD screen resolution support on MBA 2015-2017:
All MBA from 2015-2017 have Thunderbolt 2 with 20 Gbit/s, the Thunderbolt port is also capable of driving an external 4K UHD monitor with 3840x2160 pixels, you could also use these systems for streaming to a 4K TV. And to not forget, they have MagSafe 2 plus USB 3.0 high speed ports, even two. So you can also easily hook up an external hard drive if you want to stream e.g. videos or music.
4 or 8 GB RAM?
8GB RAM is important to have and using Open Core Legacy Patcher you can also run MacOS Ventura, Sonoma or even Sequoia.
SSD replacement
The SSD can be replaced, it is not very difficult plus the battery is replaced in 15 minutes. There is definitively a lot of life in these "old" computers left, they have excellent keyboards and very good trackpads too.
Difference 2015-2017 models with Core i7 2.2 GHz
These 2015-2017 models, if you can get one with the Core i7 2.2 GHz CPU, and if they have 8GB of RAM they are exactly the same, there is not a single change so it would not matter having one from 2015, bought in 2016 or even 2017.
Multiple OS
If you install a 1 TB SSD in it, you could split it up into 333 GB for MacOS, 333 GB for Windows 10 and 333 GB for Linux and run this as a triple boot system and because it has a 16:10 screen (okay not the greatest resolution, true) you would see more content than on any 16:9 computer that can be had for more.
Value for money
When you consider that you could buy one of these really still very capable computers for 150 - 200, what else do you get from other brands in the same price range? Not much of quality, that is for sure.
Such a MBA is an excellent project also for people who are not blessed with high income, considering replacing the battery for 30-50 and you get a really cool looking and very affordable and usable modern looking Apple product.
2015 and newer and at least Monterey: option + command + r
Getting to Monterey is by the way super easy, these MBAs all have internet recovery, hold down option + command + r, and the internet recovery will let you install the latest supported MacOS on these MBA from 2015 ongoing. I saved a MBA 2013 with 4GB RAM and 256 GB SSD and did not know this trick, so I ended up with Mountain Lion and could not get to the Apple Store, but using option + command + r would have saved me a lot of time to directly go to Big Sur without trying other MacOS first
