Go books to a new level

Go books from smartgo brings Go books to a new level. I bought many books I already had in paper format but to be able to read them in such an interactive way makes it worth it to pay for them all over again. Reading invincible play by play is much more enjoyable, playing through an interactive problem book is also much more enjoyable. I can only hope for more books to be published.
