The company will in several markets, and both will bump the cap to at least 300 GB for all users. In one test, subscribers to higher-speed Internet will get more data, and in the other, everyone will get 300 GB. Users who exceed their limit in either trial will have to pay an overage charge -- possibly $10 per 50 GB.

This is good news and bad news. Streaming video services such as Netflix and YouTube gobble up an increasing amount of data, and although most Internet subscribers consume nowhere near 250 GB per month, Comcast is at least acknowledging that it must offer more data for subscribers who do.

Still, Comcast's increased data allotment feels like a distraction from the main policy change, which swaps hard data limits for overage charges. In the past, Comcast cut off users who exceeded their limit twice in a six-month span. In Comcast's trials, subscribers who use too much data will simply pay extra, just as you do for exceeding the limit on a smartphone data plan.

I think overage fees are better than yanking your account, but if Comcast really wanted to take a consumer-friendly approach, the company would just throttle users who go over their limit, or at least give them that option. Instead, Comcast wants to turn heavy data users into a revenue opportunity. It's not ideal, but it's understandable from a business angle.
