Do NOT under estimate the importance of this decision!
If the Courts say the Bells don't need to allow consumers to choose what they do on their networks, it could potentially open an entire can of worms. If operators are allowed to legally discriminate against services they don't like, customers will be stuck using those (overpriced and / or crippled) the carrier chooses for you.
This primarily effects data transmissions on wireless networks such as cellular, EVDO, EDGE etc... But it does affect
ALL public shared data networks.
However, allowing such anti-trust, anti-competition opens the doors for the same thing on other networks, even deprioritizing data packets you send from and to your home and work networks.
An un-equal internet hurts everyone except the huge Telecos.

"Not using
our service?" :up_to_som "We'll just take our time with your request, if ever"
Net Neutrality is an issue the Telecos love to muddy with mis-information and lobbyist money.
