Six million instantly obsolete Surface tablets poised to flood the retail channel

According to David Gilbert at the International Business Times, this means there are about six million unsold tablets in inventory, shortly to flood the market at deep discounts. What should we do with these? Jailbreak 'em, install a free/open operating system, and use them as control systems for projects too complex for Raspberry Pi or Arduino? (via /.)
