As I wrote one of the more popular sound editors as an undergraduate (Resound), them's fightin' words. SoundKit was still quite good, even if MusicKit sorta died with the DSP.
I think I'm mistaken about OpenGL, my memory is fuzzy. As to Java: what I was thinking of was OPENSTEP/NT and NEO both supporting Java (WebObjects had Java as early as '97), but I believe it was never released on NeXTSTEP. I guess that doesn't count.
I do miss Renderman on the desktop. Maybe not very practical, just really cool.
When I was contracting at Swiss Bank in Chicago in 1994, I noticed an HP on the network running NeXTSTEP. I telnet'ed to it from the NeXTStation on my desk, and ran some renders to see how much faster it was. Got a stern email saying "Stop doing that.".
