Along with some really solid arguments about why compact discs are less and less relevant, Mark Cuban coins the phrase "concertpodding." Bring a laptop to your merch table, and let folks hook it up to their own MP3 players for $5 to download your album, or even a copy of that night's show. Scared about bringing your laptop to a gig? Buy a cheap refurb from the folks at TechRestore, or pick up something on eBay that's already been banged around. You break even on the investment after about 100 downloads.
