Re: Software was it....
Software availability was so bad that there wasn't even an offline usenet client for years - the only native ones available assumed you didn't pay for dial-up local calls.
Changi (not a Usenet client in itself, but a local news spool thingie like leafnode)
Mail clients were bloody terrible until PMMail.
That's what kept me on OS/2 (eCS) until about two years ago.
There was a decent graphics package but I can't for the life of me remember what it was.
PMView.
