Hi--
I've been following this project almost since its conception as OpenBeOS. Though never a real BeOS user (played around with PE, thought it was interesting, but thats about it), I really like the idea of recreating BeOS. Why? Because I see it as one of the few open source OS projects thats currently NOT in a mature state (like Linux, *BSD, and now OpenSolaris) that I can really see getting off the ground. The big advantage being that there is already a strong BeOS community along with a host of BeOS apps and drivers, both open source and proprietary. Achieve binary compatibility, and you instantly have a viable platform capable of doing lots of cool stuff. You also have a whole bunch of users who will be jumping at the chance to try it, report bugs, and make suggestions for extending it. Haiku also has a more feasible goal than a project like ReactOS, because the OS it seeks to recreate is well designed, clean, and clearly spec'd out.
