I never do.
Really, the biggest change in Windows 8, is that I have to press the windows key when I login. Nothing else really changed in the OS for me. I still just hit win+r for the "Run" prompt, or click a shortcut in the number of places I've aggregated them that make much more sense than Win 7's start menu layout. I got Windows 8 because it was just $15 for a valid windows license.
I'm in full agreement that there's no reason to upgrade from windows 7 to windows 8. But if you get windows 8, it's not the end of the world (unless you're really married to the start menu). Or hell, if you really need the start menu, just go download it and install it. If you're on slashdot you should know how to do this. This askslashdot is kind of a no-brainer.
