I have At&t and will never go back to insight or time warner. Had At&t for a year now never lost service, never had any slow downs. I just got cable from them and its not the best sound delay every once in a while, reminds me of old godzilla movies. Back to the internet, I do have an advantage with being right next to the fiber box and having a dedicated line ran straight to my house. Its nice no sharing on a community line like insight or time warner. Ok well there's my two cents.
