We have a Comcast cable connection. Although I just heard Glenn Beck say that he's sure the anti-christ will come from Comcast. We're pretty happy except for the fact that I still don't have remote access to my email. So I used a yahoo or mail.com account, which is a pain.
I previously had Mindspring, which Earthlink bought out, Mindspring was generally better. My office computer is Earthlink dialup, it's fine also.
