300GB might be plenty for people who are just browsing the web and checking their e-mail. But I just checked, and my average usage over the last 3 months is 700GB. That's for 3 people, streaming Twtich and Netflix and Pandora, and downloading games from Steam. I don't think this is an extreme use case, this strikes me as average. There is a helpful note on my usage page which states "Enforcement of the 250GB data consumption threshold is currently suspended". I think that, instead of up-charging people who go OVER 300GB, they should be offering a deal to people who stay UNDER 300GB.
