I am biased, but here is why -- here is my review of BeOS v5, from 23 years ago. https://archive.org/details/PersonalComputerWorldMagazine/PCW%20200007%20July%20Created%20From%20PCW%20Cover%20CD%20%28No%20Cover%29/page/n50/mode/1up https://archive.org/details/PersonalComputerWorldMagazine/PC... Haiku is also, I'd argue, the highest-profile FOSS OS that isn't some form of xNix. (Waddlesplash will wade in and start arguing now, but that's OK, you can ignore that.) Haiku is a modern FOSS recreation of BeOS that can run BeOS binaries natively, and uses the same desktop because Be made Tracker open source before it imploded. So, still alive in a form, famous and celebrated and covered in the mainstream media at the time. Also: * The subject of a high-profile lawsuit between Microsoft and Hitachi. * The subject of an Apple acquisition struggle with NeXT over who would be the new MacOS. * Indirectly the basis of the final version of PalmOS, the #1 handheld OS of the 1990s. * Also the basis of YellowTab/Magnussoft Zeta. * And of numerous remixes such as BeOS Max. Only "forgotten" if you weren't paying attention.
