I agree with you, but I have one more reason for keeping them separate. When one crashes, I don't want both to crash. This was more notable with crash-prone Unix Netscape 4.x apps. At the time, I ran two instances of Netscape (ISTR some reason I was forced to use it for mail at the time), one for mail and one for browsing.

Now that Netscape 7 (I don't feel like spending hours trying to get Mozilla to compile under Solaris, and the binaries just don't work for me) seldom crashes, I'm back to using the same binary for both things, but I'm still opposed to it. They should really be two different apps.
