I think the Amazon Fire TV will replace my current recommendation for the Roku TV as my favorite “Over The Air” receiver. Just like the Roku TV, the Fire TV will have the ability to pause and rewind live TV.
However, Fire TV adds the ability to pull up a TV Guide. A feature I sorely miss from my cable days and I supplement with a TV Guide app on my phone.
