In my case, it doesn't work so I'm not paying for it.
I will promise the AROS team one thing, when it works correctly and I'm using it then I'll make a donation to the cause.
Like Franko, I pay money for things that interest me. I bought a C-One board, I bought one of the early Minimig v1.1 boards, I've bought a Chameleon and I've bought a FPGA Arcade all because I want to help them get developed and released as commercial items (except for the C-One which morphed into the Chameleon and the Natami, but then it always was a dev board).
How do I put this? AROS isn't a company, it's not a "Team", it's not a project, it's a source code repository. This source code is free for anyone to use and when compiled generates software that clones AmigaOS. This source code is added to and improved by members of the Amiga community.
You can't donate to the AROS team, you can simply make requests for features/improvements and add an incentive to inspire a coder to take up the request. Whatever is the result of that, become part of the AROS code and is free for anyone to use. It is a community effort, by the comment for the community.
I realise you might not understand the opensource movement so this can seem alien, but the end result is worth the effort. I have donated both money and code to the project and I would expect others to do the same if they want the Amiga to still exist in 20 years.
You say it doesn't work, I know then that you haven't even tried AROS68k...
