I'm a happy user of this tablet.
I also created a [Go app](https://github.com/juruen/rmapi) to interact with the cloud API.
I mainly use the tablet as a "virtual printer". Using the app I just mentioned above, I print directly to the device from my Mac. Yeah, this just saves me a couple of clicks and one drag and drop :)
Here's a [tutorial](https://github.com/juruen/rmapi/blob/master/docs/tutorial-pr...) on how to set it up and an actual [demo](https://www.youtube.com/watch?v=gOGTYI15VxY&feature=youtu.be).
When I was studying, it was also great to use it to solve math problems on it when I was traveling without having to carry too much paper with me.
