Well, I have the Remix Mini http://www.jide.com/en/mini bought at the Kickstarter campaign and I'm really enjoying it. I don't have any PC (or Mac) at home because I don't use much and it is being my home computer for when I want to see something on a bigger screen (despite of the Nexus 6P screen be huge!).
The only think that I don't like is that the user experience is really laggy. Although I have the 2GB version (with 16GB of storage), it clearly need some more RAM (3GB or even 4GB). That's why RemixOS for PC should be a good approach.
Regarding the OS itself, when the hardware isn't trying to keep up, the usage is very good and the multi task windowed launcher is really well made. I can see a great future for Remix OS, but I'm really excited about Microsoft Continuum!
If you guys are looking for some alternatives for Remix OS, you could try the Phoenix OS [http://www.phoenixos.com/] (http://www.phoenixos.com/). It is also based on Android x86 and have similar features as the Remix OS.
