I would guess somewhere around 40 MB, just enough for your personal presentation to hand out at tradeshows, or an interative resume to hand out to potential employers.
So you can't burn to them? I guess we'll have to buy em, but at $8 a piece times 20 = $160 then shipping/tax. I'm not sure i'm that desperate to get a resume out for that price. Paper will do nicely or a regular cd-r if I want to go fancy.
