Asus is no stranger to doing interesting things with Chrome OS systems, but none of those experiments have been as small or inexpensive as the Chromebit CS10. This little computer puts a complete Chromebox in an HDMI stick that's only about the size of a first-generation Chromecast, and it'll set you back less than a Benjamin (not me).
The Chromebit CS10 shares a lot of DNA with Asus' cheapest Chrome OS laptop, the Chromebook C201. A Rockchip RK3288-C SoC with a quad-core ARM Cortex A17 CPU and Mali T764 graphics is fed by 2GB of DDR3L memory and 16GB of flash storage. There's no microSD slot for expansion. Dual-band 802.11ac Wi-Fi and Bluetooth 4.0 handle wireless connectivity.
Those guts are wrapped in a package that measures 4.8" long by 1.2" wide and just 0.67" thick (123 x 31 x 17 mm) and weighs 2.6 ounces (75 g). The power supply is an external affair, so it adds a little bit to the total size. The CS10 has just USB 2.0 port for peripheral I/O. The HDMI connector connects this machine directly to a TV or monitor.
Asus says the Chromebit CS10 is available today in black and tangerine orange. When it shows up at retailers, it'll carry a suggested price of $85.
