For all you new Fire TV owners, today is a great day to build up your app library as Amazon has reduced some 'must have apps' to free. Here are some links and recommendations...
http://www.aftvnews.com/ (everything int he right margin)
free apps sorted by rating
at least get...
Plex, Sonic, TuneIn, Tetris, Terraria, and angry birds space
For people with kids, I see the Living Books being added pretty quickly. These are not free, but at <$5, they are much cheaper than I paid for the PC versions when my kids were small.
