I have bought 4 books and a dictionary in the approximately 4 weeks I have had an ereader. About $70. It would have cost more than double that with shipping and duties and perhaps even more if I bought them locally, supposing they were available.
At that rate it will take about 9 months to pay for the reader. I think that is deceiving though because of the free books available. I have an ever increasing list of books to read that I haven't had to pay for. I am not even keeping pace with what is being posted on this forum. I have stopped loitering at certain sites with free books because it is starting to depress me. Baen is now the bane of my marriage. Harry has 15 000 ebooks!!! At first read I thought he must be a nutter, but I seem to be heading in the same direction so I need to urgently reassess my definitions in this regard.
I love reading but I have never been hugely enamored of the actual physical books. The ereader is a wonderful thing. It constantly makes me feel all warm and fuzzy in side. Now if only this bloody Xmas rush of photography would end so I can get down to some serious reading.
