I have a pretty old Intel MacBook Air, 8GB RAM, 128GB SSD. What could I use this for instead? Any chance to install Linux on it and "do something"? Currently it's a literal paperweight on my very messy desk.
I'd wipe all personal information and sell it. I've never liked the idea of having unsupported OS's in my house connecting to the internet. I don't know that linux would add to its usefulness if you have much more powerful computing hardware at your disposal already.
