I recently purchased an iPod Touch 4 and was wondering which eBook app takes the best use of this (display). Price doesn't matter. Based on the research I did already, I find that most users like iBooks, Stanza or Kindle. What do you think is the best? My eyesight is fine and I read a few hours a day, usually during the day and maybe a quick 15 - 20 minutes in bed. Also sorry if this has been posted before, I just thought with all the latest updates to the apps things might change.
