Several awesome new features: Radio or TV broadcasts—this means I can go from Castiglione to Rem Dawg? Yes please. All Scully, all the time? HELLS YEAH.

Four games at once? no commercials? I can watch the Yanks lose and the Sox win no matter where they are playing? Niiiiice. (this assumes that the Sox pitching is more than a Colonel’s Bucket, a Sam Adams, and the remains of Josh Beckett.)

Free app? Fantastic. I will never miss a Sox game driving home from [redacted], and can pick up games from Safeco, Petco, Dodger Stadium as they start when I get out of class? No more tuning in the blowtorch 880 AM from New York  just to hear some baseball? No more Susan Waldman is worth the price of admission alone.

Fantasy team connection? Deeeelightful. I have a crown to defend.
