Of course, you'll still need a Netflix login. But if you're like most people, you'll just "borrow" your parents' or cousin's username and password.
The deal is basically a win for everybody involved, as Comcast customers get easy access to their Netflix, Comcast incorporates Netflix's original content, and Netflix gets more potential customers through Comcast's massive user base.
This all comes after long-standing tension between Netflix and Comcast, as Netflix opposed the now-failed merger of Comcast and Time Warner Cable, and following Netflix CEO Reed Hastings' accusations that Comcast violated net neutrality rules.
But when everyone stands to make money, well, egos seem to be able to take a backseat. And this time, you, the customer, win, too! (Hopefully.)
