I am considering getting the Kobo ereader. It seems to be the one I like the best for the best price. Originally I was totally against them as I have an issue with buying books I can't physically hold other than through some electronic device. But I am finding it difficult to always carry the book I am reading with me. I am curious as to whether they are truly worth the $150 plus the cost still buying the books to put on that I can't find to download?
