BeOSBe, Inc. BeOS.
Be, Inc. sold its intellectual property assets to Palm, Inc. in late 2001 and then it is dissolving.
Travis Geiselbrecht used to be a Be kernel engineer; he wrote NewOS after he got laid off. IMO, BeOS was one of the best systems ever ,in that it boots in +/- 15 seconds (faster than anything I've seen except maybe CP/M-86 ;-). Also, again IMO, it's truly crash-proof-I've never had any problems with stability. I recommend getting the current BeOS 5 PE Max distro from www.bebits.com. The Max distro's are free CD images, so go ahead and look for them. As of this writing (02/07/03), the current version is Max 2.1, and it's a 223MB .zip file (includes Nero cue files and patches to make it work right on Pentium 4 and Athlon XP systems).
