I prefer to use the nook ap (Barnes & Noble E-Reader) on my smart phone. I don't carry a purse and would rather not have to carry around one more thing. I have to flip through more pages than I would on a real E-Reader but a real E-Reader doesn't fit in my pocket. Also, I've all ready paid for my phone so I don't have to buy another gadget & can spend more money on fabric!
The one thing that really irks me about all e-books is the price. Why on earth do I have to pay more than paperback price and in some instances--more than hard cover price for an ebook that I can't even give away! That makes no sense to me. At least I can gather up my paper backs and trade them 2 for 1 at the local book store but e-books, except for Barnes & Noble's "lend me" feature which is still annoying, cost more! I do scarf up any and all free e-books and others that are less than $5 if it's an author or subject that I really enjoy and gets decent reviews.
