I've not touched a dotfile in a decade+.

One thing that people fall into is the ability to tweak things endlessly. If you simply don't do that and use a good default install then you are going to do just fine without all that tuning.

For me my main tools are shell, browser, various audio related programs (audacity, midi editors, score editors and so on) and installing a new linux machine takes about as long as copying the data off the medium takes. Then I copy over (or mount, depending on the circumstances) my homedir and get to work.
