BeOS had a POSIX-compliant layer, but under the hood it was totally different from a UNIX. Also, let’s keep in mind that Windows95 (released that same year) featured preemptive multitasking on a desktop user OS (albeit not a strong memory protection model), and WindowsNT has been available for a couple of years by then (having first shipped in 1993, If memory serves) and was a fully ‘modern’ OS (indeed it serves as the basis for the latter Windows), albeit with a comparatively large footprint. I was an avid BeOS user (and coincidentally a NeXT user too) and I was enthralled by its capabilities, but in terms of system architecture it was a dead end.
