Zink (2007) = Polaroid (1963)?

I’m not sure I get all the Demo excitement over the Zink micro-sized printer.

While I applaud Zink for the environmental aspects of its product (no printer head cartridge = less waste), I can’t help but find some irony in using state of the art technology to replicate Polaroid film. Do people really want to print photos “on the go” that badly?
