Chatbooks

Do you have chatbooks?  I don't, but I'm seriously considering getting the app after seeing their commercial.  I was waiting for a youtube video to play this weekend, but got stopped by one of those annoying ads - this one just happened to be for chatbooks.  Well, the ad was soooo hilarious, I couldn't stop watching it.  It's very effective advertising!  It's just over 3 minutes long, and you need to watch it if you haven't! :)

Has anyone used this app?  I'm wondering what people think of it.  Sounds like an easy and cheap service, and a cute way to print your photos...
