I got one of these from the Kickstarter campaign. It works reasonably well. I haven't tried to do much with it, but as a tiny desktop computer it's OK.
I had initial problems getting the display to work, because my monitor (a Benq GW1255) only accepted 1080p on its HDMI interface and the Remix output 720p. I first connected the Remix to a monitor that could handle 720p and changed the Remix's display settings, but I finally ended up getting a HDMI to VGA connector (from Amazon by CableMaster, about $10) and it now works fine.
I use the Remix just for playing around. It prints fine with a Brother driver over my wifi to a 2360DW.
I use my Apple keyboard (wired) with its attached trackball via USB, and they both work without any problems.
So far, I like it.
