i HATE cox. before i moved, i had roadrunner, which was 2.5 Mbit/512 kbit. now i got cox and i cant even pull 1 Mbit down and my highest upload is 15 kB/s (bytes), where w/ rr i did 60 kB/s up. BAH!!
Cable is shared throughout the neighborhood but u can be farther away from the central office (or watever u call it) and keep good speeds. w/ adsl, the farther u get from the central office, the less speed ull get (very noticeably compared to cable).
also, cable has a lesser bandwidth limit than adsl, friends in newyork can do 10 friggin Mbits!!! FOR $60-70/mo USD! BASTARDS
