Right now it's vapour, but there's also this: http://www.alwaysinnovating.com/products/mecam.htm http://www.alwaysinnovating.com/products/mecam.htm It promises better hardware (Cortex-A9 SoC, 1.0-1.5GHz CPU, 1GB RAM, SD card, 2.4GHz/5GHz Wi-Fi and Bluetooth), at a third of the price (MSRP: $49). But again, it's not real (yet?) - whereas the pre-order of the Crazyflie Nano has at least already started. And they seem to have a firm shipping date.
