Your Fire TV (or Fire TV Stick) just became much more useful as a cord-cutting device... at least, if you watch a lot of CBS shows. The TV network has launched an Amazon-native app for its All Access service, giving your Fire TV the same mix of live and on-demand viewing that CBS is offering on rival set-top boxes. You're still paying $6 per month and don't get any hardware-specific features, but look at it this way: you'll definitely be ready when the new Star Trek series begins streaming in a couple of years.
