That's not a bad idea, some of us don't have DVD burners either.
And so? What are they waiting for, to buy one? :lol:
Seriously: a DVD burner costs €15 ($ 22), and is technically hydentical to a CD-R one (you plug off the old CD recorder and plung in the DVD one, and you're ready), so the "some of us don't have a DVD burner" argument won't be considered, sorry.
More valuable is the old laptops issue: maybe I'd consider a cut down CD edition for them, but I am afraid most of them won't have enough horsepower to run modern applications (OWB, MPlayer) at decent speeds too.
