For example I've been playing with Lunapaint on AROS. And that copy of AROS is on a flash memory card that's as big as my fingernail (microSD). I would have never predicted that this was possible when I bought my first Amiga2000 in 1989!!!
Where didi you get it? I've researched in the past for the possibility of booting AROS from usb, and am yet to find a way, could you share it please?
