I also enjoy to install linux from scratch. But having a laptop available with linux installed is a big plus. That way, I am sure that all hardware problems (correct throttling, hybernating, etc.) are my fault and not lack of hardware support. I also have an example install with working drivers. Then, I do the installation from scratch, if it is for me. Or if it is for a new postdoc that just needs a linux laptop I can leave it as it is.
