I love my reader(s), but I love pbooks too! I see no reason to give up pbooks just because I have a reader. I probably do about 50% of my reading on my reader--the other part of the time I'm reading pbooks. I'm usually reading at least two books at once--many times more. Though almost always I have at least one pbook and one ebook going at once.
If I had to give up one or the other I'm pretty sure I'd give up pbooks--ebooks are just too convenient for taking with you anywhere you go. But I'm very glad it's not an either/or decision!!
