Drive Aliases are wonderful things. My Hard Drive was always HD0: but I could also call it MEERKATHD: If I wanted. And I could have an alias for GAMES: that pointed to HD0:/games or whatever.
The bit I always thought was cool, though, was the volume name on floppies. You didn't have to reference a particular drive, you referenced the disk - and whichever drive had the disk would get to work. Or it'd ask you to insert the disk.
Not exactly revolutionary, but 20 years on, still way ahead of Windows. Go figure.
