Cotton Candy: FXI technologies’ USB stick-size portable computer prototype with a dual-core 1.2-GHz Samsung Exynos ARM CPU. That’s the same processor in a Samsung Galaxy S II, by the way. Also, it has 802.11n Wi-Fi capability, Bluetooth, HDMI-out and a microSD memory slot.

Wow. Imagine the uses for this type of super portable computing, support and ops would love this. Of course, there are also pitfalls. Physical security types will know how easy it is to infiltrate a network by leaving a random USB stick in the parking lot. We humans are a curious bunch, and people can’t help themselves when presented with a USB stick.
Computer disks and USB sticks were dropped in parking lots of government buildings and private contractors, and 60% of the people who picked them up plugged the devices into office computers. And if the drive or CD had an official logo on it, 90% were installed.
Imagine if that stick had a fully-functional OS on it.
Anyway, very cool stuff.
