The Asus Chromebit, which should retail for under $99, is also a Rockchip device with 2GB of RAM and the same 16GB of eMMC flash storage as the Chromebooks. It’s basically a Chromebox on a candy bar-sized stick (I’m actually surprised it’s not called the Chromestick).
As an HDMI stick it’s clearly targeted at enterprises that may want to use it for mobile workers and maybe companies that want to use it for in-store displays (Google already has a similar program for Chromeboxes, after all). I’m pretty sure there will be quite a few hackers who will want to play with the device, too.
