Be’s TCP stack was never very good. It never had big money applications like Frame or Illustrator, and lacked the robust dev platform (and paying customers) that Next had.
And I'm using "business" in a generic sense. This was an important quality for schools, as well, where Macs were incredibly popular (for a number of reasons, including favorable pricing from Apple and historical support for schools since the 80s). Single user OSes just don't fit within any organization trying to at least pretend to have decent IT.
How has OS X's "multi-userness" helped organizations?
Do you literally mean two or more people using the same Mac?
Has it been useful for organizations that users can ssh into Macs? Or is Apple Remote Desktop involved? (Does Apple Remote Desktop even allow 2 people two use two instance of OS X's GUI at the same time?)
Or by "multi-user" do you refer to the services that can be enabled using the "Sharing" pane of System Preferences (e.g., file sharing, printer sharing, remote management, internet sharing)?
It’s not about simultaneous use, but standard user management, access control, and permissions.
Though yes, technically this also allows multiple to access it simultaneously via ssh and other things that’s not the important part for IT in this instance.
- BeOS was not a great choice, though certain aspects were much better than NeXT, primarily the filesystem. There were a lot of things missing, but BeOS's lack of printer support was the headline issue; seems ridiculous today, but "desktop publishing" still mattered to Apple at the time, and it spoke to immaturity of the BeOS graphics stack.
- Aside from WebObjects, the vaunted NeXT software stack was bitrotting. It was buggy and unstable on commodity PC hardware, and it was never polished enough for non-Unix-savvy end users. Apple spent something like six years bringing it up to a consumer-ready spec before they felt comfortable dropping classic Mac OS.
- The original iPod used no NeXT-derived software.
- But without the NeXT purchase, Apple wouldn't have gotten Steve back.
- Without Steve back at Apple, the iPod wouldn't have existed.
- Without the iPod, you don't get the iPhone.
