All great points. The customer service in particular is just outstanding. If there was the opposite experience of calling into Comcast support, it'd be calling into Charles Schwab. They know their stuff and are willing and able to patiently explain things well beyond a script. The yearly free financial consult is awesome, too.
Only annoyance is that some of the procedures require printing out a PDF, filling it in, and physically mailing it or faxing it back. Hopefully that'll be less common in the future.
