Thanks for your answer, I purchased this MacAir 2019 (2018 model) I will like to use it at least one more year, my question is if I upgrade the memory RAM I will have a better/descent performance or better do not invest on that and buy a new computer.
You seem to have missed the… And because you can’t add more memory or more storage after purchase… part, there.
MacBook Air 2018 was the first of the fully-soldered Air models: https://eshop.macsales.com/shop/ssd/owc/macbook-air
The Intel iMac 27” and Intel Mac Pro are among the last Mac models that can be reasonably user-upgraded, other than via Thunderbolt expansion.
The Apple laptops have been increasingly difficult to upgrade after purchase, and the last several years’ have ~everything soldered.
Yes… This integration is bad for buying and upgrading immediately or buying and upgrading later, but (as has been the case with increasing integration over the decades of computing) it also means denser, faster, and more reliable gear, with fewer connectors and joints to fail. Ever bigger parts get swapped, for repairs.
We’re in a trend for the entire computer to be integrated onto a single chip, and M1 is a step closer to that.
Your options here with a 2018 or newer MacBook Air are to contend with what you have, until you decide to sell it and upgrade.
