My experience may be too anecdotal to take into account, so I understand not caring about my specific experience. But I do think it’s a good idea to take life span into account, and from a quick google search the average lifespan of a Macbook air is generally 5-7 years (so really not far off).
Just something to consider that since parts aren’t replaceable, OP would have to pay the full amount of a new laptop at that time
It’s really inspiring to see such a wide range of hobbies in this thread
