I have a really hard time getting Aurora working the way all my other Linux devices so that are running some form of Ubuntu (Mate or Bodhi). With that said, it's been very stable and i like not being interrupted with packages to install while working on things...
Mixed bag review. I give it 3.5 out of 5 stars.
The Stumptown aeropress video will give you an idea of using it while camping.
I pan roast and it makes pretty tasty coffee, but doesn't work well as an espresso bean. For that I stick with something professionally done. I don't think I would invest in roasting beyond what I've done. It's a good way to understand more about the process/journey that beans undergo.
