When you are getting older, your time gets more valuable. You earn more money, but you also realize your time on earth is limited. It is no fun tweaking the same config files for the umpteenth time after installing software on a new piece of hardware.
That's why I keep a Dropbox folder called "linux_tweaking" with some of the config files. If I need to install arch on a new machine I can do it without hassle.
Also, it's true that as you grow older you value time more. And that's why I use linux in the first place. I am faster with it at pretty much anything. The only thing that really drives me mad is skype but my wife has problems with skype also on her windows and mac computers so it's not linux to blame.
