No you don't need a Kindle or Nook, there are PC apps as well as tablet/ipad apps that you can use to read Nook and Kindle books. Paperback edition could be out as soon as 2-3 weeks or as many as 10 depending on the Ingram catalog update.

Tonight I finally was able to edit the amazon page but there is no preview option so I do not know if the edit looks good until the page updates. All in all, it has been a good day. I have sold 10 copies and one to someone in the UK. I was joking with my dad earlier now that I can add the word "international" to my sales!
