This thing's about the same size as a USB stick from the early 2000s, but packs in a whole lot more. It's a dual-core computer, complete with HDMI output, Wi-Fi, Bluetooth and USB connectivity.
It's the FXI Cotton Candy, a much more consumer-friendly option for those tempted by the Raspberry Pi but a little intimidated by the latter's technical demands. For around £125 buyers get a 1GHz ARM Cortex-A9 processor built by Samsung with accompanying ARM Mali-400 GPU, Android or Ubuntu pre-loaded as the OS, plus support for MPEG-4 and H.264 video formats.
It's being marketed as a "cloud computer" to be used as a companion device for smartphones, or to be stuck anywhere there's a need for a tiny little networked video player. A mobile without a screen, to do with as you please.
