Jumping in here without reading the whole 
thread (which is par for the course for me), but I have a Nook Color (Barnes and Noble's ereader).  I find lots of free books there.  I also signed up for bookbub - 
BookBub: Free and Bargain Kindle Books, Nook Books, and more - and I get a daily email with free or discounted books.  I imagine the link has already been posted here, but for others like me who don't have the patience to read through a whole thread, there it is again 
Right now I'm reading "Worth the Drive" which I did pay $0.99 for.  It involved golf, and those of you who know me from the Women's Room know I love golf almost as much as I love cats, so I didn't mind paying a buck for it.  It's good! And over 900 pages, which ain't bad for a buck!  When I was looking for it, I realized the first book in the series (I think it's called Worth the Wait) is free!  I downloaded it but I haven't read it yet.  Had to get right to the golf-related book!
Anyway, if you haven't signed up for bookbub, I recommend it!  Some days none of the books in the email are free, and lots of days I don't download anything, but I've got such a backlog now it will take me quite a while to get through all the free books waiting for me!
