Windows XP

WinXP settings (needs WinXP SP2) - nice set of colors and fonts.  Also disables a lot of WinXP eye candy and makes your machine zippier.  Use the "Files and settings transfer wizard" to load this.

Unix stuff 

FVWM2 rc - Losely modelled after Robert Pike's Acme: A User Interface for Programmers, and VI like keybindings.  I've used this for nearly 8 years now, and don't find any reason to move to Gnome/KDE.

GNU Screen rc - nice settings.

Vim rc - The culmination of years of happy Vim hacking.
