Still have Warp 4 (with updates) on 2 machines and love it. Still amazes me how much was packed into so little hd space. Runs great on my 200 mhz machine.
Buy hey, I still have my Commodore/Amiga machines up and running
Having said all of that, OpenBSD is my main/primary OS.
btw- if you go to the ecomstation site, you can download a demo to see what it is like now:
