And what is your favorite format? For me its never simple: Mostly on my android phone using: Cool Reader - ugly but will read a standard epub aloud Kindle App - far too many books locked behind the Amazon wall Barnes & Noble App - clean, easy, imports epubs I prefer epub for general reading, PDF for picture books, magazines, manuals And for comics I use perfect reader for cbz,cbr formats On my very old iPad mini almost always apples books and epubs And on my Windows tablet ( because I couldn't afford a new android tablet and this one was CHEAP) Kindle app, perfect reader, sublime text, and foxit PDF reader And yes there are a half a dozen very old actual Kindles running around the house. I read on two of them. My version do star Trek PADDs. Yeah I know I'm complicated ...and I have an idea..... But I need some answers. What apps do you like ? Where do you read Ebooks the most? What features would you like to see in an Ereader that you currently don't have? And even if you think you've guessed right, *just* another Ereader is NOT where I'm going with this. Remember my goal is to help you write the books AND sell more of them. Stay with me folks.
