Great book... and one I don't regret purchasing two weeks after I bought it! I was hoping there to be a discussion on the "conversion" process between say pico or dos-edit to vi as that's the biggest problem right now. I really love the vi editor now but I don't have the "feel" for it as I do for "standard" editors (ctrl-insert copy, shift-insert paste as well as block selection). As a suggestion please look into a chapter on the "conversion factor" topic.. Other than that kudos on a great book.
