Linux cannot answer it all for me. My one user has AOL dial-up (for some reason i can't figure out). However, they are many AOL dial-up users out in the world stil.
The problem is that none of the current distros I have found can handle any interaction with AOL dial-up. Peng (Penggy/PenAOL) was the most promising program for this, but they seem to have abandoned the software, and it seems to have been dropped from most repositories. I can't even get the source I can find to compile correctly on Ubuntu, Fedora, or Suse.
As much as AOL is crap to me, it is somehow easier for older folks to understand (until they get their first HTML-formatted email in the crappy plain text interface). I think that these folks are still very much in AOL's prime target audience.
Until I can set up a linux box again, with dial-up to AOL, and pulling email into Evolution (which is easy as cake), I have to support this box on a windows environment.
