Next Linux question:

My new laptop has a 2TB drive. Once I obliterate the windows install (I mostly will update the firmware for everything first, save the windows key, and then nuke the drive), how would you partition it so that I can install 2-3 Linux flavors? Or would you not bother and just use VMs to play with other distros?

In any case, I want to save my data on a separate partition that would be visible to all OSs installed. I also want to be able to roll back dumb changes I make so it seems I'll want to use btrfs?

I will not bother installing windows onto this laptop, at all, so that's not a concern.
