When was the last time you have used the B: drive?
Anyway, an interesting thing is that growing up in Russia, using DOS, we were all gung-ho about using Norton Commander and its clones, such as DOS Navigator, to supplement the vanilla command-line DOS experience.
And I'm telling you, it was oh such a great experience, that to this day, I still wonder how I manage to get by in my vanilla command line bash shell. Sure, all the auto-complete tricks are insanely useful (and maybe that's all we really needed?), but I recall the whole two-directory layout was super useful in being able to move files around and do quick edits and what not. Midnight Commander just doesn't do it for me. I tried FAR Manager on Windows, and also no dice. They all feel heavy and not as natural.
To put it into perspective, anyone who's really really into VIM, think about how you love how fast you can be with VIM, despite the obscure key combinations and the modal overhead (haha, bias showing?). Anyway, think about how once you get used to all that power, you wonder how you can survive without it anywhere else. That's what using Norton Commander /DOS Navigator was like in MS-DOS. Using a Solaris/HP-UX command line circa 1998 felt like going back to stone age.
