As long as I don't grow a UNIX beard

Slowly I am becoming immersed into the world of the UNIX user. Earlier, I was griping about how obnoxious it is to not be able to use UNIX commands on the Windows command line. Then, I bought a tinylaptop that comes with Linux installed. Then alicia250 began persuading me to change my OS to Ubuntu after I reinstall on my desktop, and wy1d began offering pretty promises of dual-booting.

Someone remind me why I shouldn't do it.
