No, BeOS is not dead as many will speed to the forums and proclaim.
YellowTAB's Zeta is the true inheritor of BeOS 5's fortune, as it is based directly on Dano/EXP's codeline (which was supposed to be BeOS 6 but was never finished as Be sold its IP to Palm). At last, I got my hands on Zeta Beta-5a, and here is what I found and think of it so far. You might need to have some experience with BeOS in order to follow this article, but screenshots are included to make it easier for everyone.
I should say it's not as dead anymore with Zeta, but it is dead in terms of mindshare, just like the original. When you don't have mindshare, open source is the best way to go.
