Funny, I actually used Netscape 4 on the 486 for a short time before I figured out just how much faster IE 5.5 (6.0 SP1 on 98lite) is on the same machine. Night and day difference -- but Opera 8.50 is the best of all worlds for such a machine, it can render more modern sites than either and has tabs while still running acceptably within 32MB of RAM on a DX4-100. I never bothered with the email component -- I use ProtonMail, and the Bridge application only seems to work for serving to an email client running on localhost. It requires TLS anyway, something I'm pretty sure Communicator 4 has no concept of. If I ever get a VPS and domain like I was wanting, I might see about it then...
