I tried out the read-only version. It's not bad. A little buggy. It crashed a few times. I could see myself using it if I just wanted to check on a post real quick but given the limitations of the free, read-only version I'll probably just continue to use a browser to read CS. There is something about tapatalk that takes away the "authenticity" of the board, plus I don't get to see everyones awesome sig tags.
