Yes, I have the framework laptop because it’s designed to be Linux compatible. I put pop_os on it and everything just worked with no tweaking.
My employer didn’t truly provide it. Using Linux is one of my hiring requirements and they told me to provide my own machine. But employers should really look at framework machines if they want something repairable.
Not currently in the open source space, although that is a possibility in the near future. But all the software I’ve made in the last several years targeted Linux anyway (except for UIs but those are web or react native). I reached the point where I was tired of dealing with windows and macOS at work. So I switched jobs and started making this a requirement. I ask about it in the first interview with any possible employer.
Probably not something you want to do when you’re a Jr Dev, but props if you can convince them. When you become a sr/principal/architect level most employers give you a lot of flexibility.
