The device works perfectly, I've made the boot SD-card with Linux image, connect the device to a display with HDMI cable, plug a keyboard and mouse, Ethernet and microUSB cable (for power supply). And it loaded and run.
Unfortunately, there isn't a Russian keyboard layout (so I write this post in English), an there is no way to make a sreenshot.
But it looks beautiful! It has the browser Midori (I am writing this post in it), Python and some toy programming language "Scratch", like a some visual algorithm builder.
