I virtually NEVER use the command line anymore. OK, that's not totally true, but I can go days without requiring it. I've been using AutoCAD since 1989, so I'm an "old timer" in it, I loved the command line. But after 3 days with it off I swore I'd never go back to having it on...if you know the commands (and to an extent even if you don't) you simply don't need it.
