I have a Nook and an iPhone. They also have a Nook app for the iPhone and I have that one. I tend to not use it because I usually have my Nook with me when I would have a chance to kill some time, although sometimes I do get caught out without my Nook and will use the app on my phone.
I have an iPad and use Stanza mostly, but I've started using iBooks some because it's easier to transfer books from my computer. Stanza has more options as far as looks (screen color, text color, brightness) and instead of saying page _ of _, it gives you a percentage, which I really like.
What type of device do you use? For the record, I'm using an iPhone, but I would like to hear from other device users as well.
What ap are you using? Are there more than just the kindle one?
Where do you get your books from?
Do you like reading this way, or is it only in emergency situations that you use it?
Thanks for your responses!!
