Only thing is they haven't upped the bandwidth caps (which are still 250GB per month).
To put in in perspective, if you actually used your full 30Mbps you would use up your maximum monthly bandwidth on Comcast in less than 19 hours.
ISP's need to learn that giving us more speed while at the same time putting in monthly caps that actually prevent us from truly USING that speed is simply a half-measure.
With the rise of streaming video, online movie purchases, and episodic new-media content (podcasts and the like), they're going to have to start rethinking their cap mentality.
