Changing Habits: Kindle

I've been a Kindle owner for about a year and a half (I'm on the Kindle 2 now). A few observations about how my reading habits have changed:

* I read more. A lot more. I have 70 titles, which averages out to about 3.5 books a month. There's no lag time waiting to get the next book from the library or bookstore. As soon as I finish one book, I start the next within 24 hours.

* I've become a series snob. What I mean is that I prefer books that are part of a series, at least three but the more the better. The boundaries between one book and the next are almost non-existent. I barely notice the titles of books in a series, and after I read one I'll often buy the rest of the series all at once. Thereafter, I go from one to the next like they're all one book.

* I have little conception for how many pages a book has. Occasionally I'll notice the page count when I'm buying a book, but after that I might only notice that my percentage of completion is going quickly or slowly.

I'm happy with the device, but I do find myself wondering why I'm buying all these books (if I am indeed buying them). I'd rather pay Amazon a monthly fee, or pay much less to just rent a book, like a library. It's a big enough issue that if Amazon doesn't change it's tune, I could see myself moving to a device that does.
