I haven't made an audio CD in years. I carry multiple 2Gb external hard drives for my laptop and my iPad and iPhone (both carry needed music). I have a complete backup laptop kept in the car for bigger events .. otherwise I can get by with the tablet.I've been thinking about getting one of those 1U all in one units like that. I only take a few CD's that I pre mixed just for a back up, but a duel player and controller takes up 4U spaces so I may pull that out and go with something else someday.
