Sorry for the delay in getting back to you on this topic, BMX -- I was celebrating my birthday this weekend (it was actually today, on May 16)...
Yes, I can see where the computer's editing software would eliminate all the hassles of these recording "errors"; I see your point clearly about that. With standalone CD recording units -- whether they be professional grade variants like my TASCAM, or so-called "consumer" grade decks (not really found anymore; these are the ones that will not accept "data" blanks and can only record to so-called "audio/music" CD-R media) -- if a mistake is made during recording, and the end user is utilizing a CD-R (not CD-RW) the mistake cannot be undone, and thus a "coaster" is burned (a worthless blank).
Still, I do prefer using standalone recording devices like these CD recorders; I wonder, though...does computer burning software, even advanced types, allow for CD-R (non-rewritable) media to be manipulated when errors are already recorded?
