I mentioned Novell in my essay and how its revenue declined quickly after they moved away from NetWare, including Client Access Licenses.
Linux killed them...and it was time for Netware to go. I remember the first time I compared Border Manager with OpenSuSE (2.2 kernel -w-w ipchains) & squid as proxy. Eye opening. No more midnight reboots. No more opaque interfaces and $$ for nothing.
