There are many different methods through which one can develop against/on Linux. For example, I have a pretty low spec'd Macbook Air and several different test machines at home that I do remote development against. I prefer a low-heat, high battery life, good performing machine like the Air over a power hungry, loud, and constantly overheating workstation. But, those are my preferences -- some people want to have a single interface through which they do all their work, and the most powerful Linux laptop money can buy. If that's the case, Framework is great!
