Kovid, you never cease to amaze me. three years ago you saved my sanity when I got my Kindle DX and now you have done it again with my new Fire. Project Gutenberg was exclaiming all over their home page that there was no point buying the Fire because it would prevent us from reading its MOBI versions of public domain books. A quick click of "send to Device" and I am reading all my Gutenberg texts. I LOVE CALIBRE!!!
