I want to share this interesting article that was written about Daniel Robbins , creator of Gentoo Linux and later Funtoo Linux , for the blog "What He Uses".
The only mention is of the computer he owns (a MacBook Pro) and what he uses on it. The surprising thing (and he assumes it might be surprising) is that he uses Windows 7 and Mac OS X Lion interchangeably , and that he avoids using Linux on his desktop because "it distracts him from his goal, which has to do with the inner workings of Linux (and not with the GUI)."
He then adds: "If I set up the X server, I usually spend a week trying to fine-tune font rendering, and then the idea of ​​creating my own desktop environment comes to mind... but I need to stay focused :)".
Someday I'd like to create my own Linux desktop environment, but I'm a very perfectionist and a moderately good graphic designer, so I'd have to be really good to please me. "
