If you were talking about OS4.x on the Raspberry Pi then I could get excited. Even emulated systems like the A.L.I.C.E. look fun but AROS doesn't cut it I'm afraid.

However, a port of AROS to RPi is not enough... to go mainstream, there needs to be branding / marketing / an eco-system to attract users... through the RPi this could be the route to tens of thousands of users... or more!
What happens the day when tens of thousands of AROS users discover that their operating system of choice is by design is one entire security flaw in itself, that allows any code running on the system to access the entire memory and all of the hardware, without the user having any saying?
Do you want to be the support line for something like this?
