@Tomas,
I agree!. Beos was the new Amiga for me. It just flew on my 500 Mhz PIII. I had that machine dual booting Beos 5/ Win 98. Beos made Win98 look like a joke on the same hardware.
Actually I read that one of the main reasons Beos finally died was because Microsoft bullied the hardware companies ( ex: Dell, Hp) from offering dual boot machines with Beos. It would be very different world right now if this had not happened.
