You might like Haiku, then.
I view the collapse of Be as story about the many failings of the broader tech industry and the irrationality of the dot com bubble and not in any way an indication of the technical merits of the BeBox or BeOS.
Anyway, Haiku as it is today is kinda like what BeOS was back then but obviously incomplete in several really important ways. Meanwhile the world has moved on and I do everything I used to do in BeOS (and more) with Linux. Though I do wonder what BeOS might look like now had they not collapsed back then.
