I have a Kindle 2 and I love it!! I have over 400 books on it. I re-read alot of my books.
When concidering buying an eBook reader, keep some things in mine.
1. Seperate DRM books from non-Drm books.
2. Look at eBook readers as a tool to read DRM books.
3. Look at where you buy the majority of your physical books.
For me, before I purchased my Kindle, I purchased 90% to 95% of my books from Amazon. So, it was a given that I would purchase a Kindle to read DRM books. Now I get 98% to 99% of my books from Amazon.
To read non-DRM books, I knew that there were converters that will convert eBooks to differant format, so I went looking.
The best one I found is
calibre - E-book management. Basicly what you do is:
1. Add any non-DRM eBook in any format to the Calibre library.
2. Connect your eReader to the computer.
3. Select the books you want to copy to your eReader and click "Add to device".
It will automaticly convert the select books to the format the eReader can read, save the converted copy, and copy it to the device.
This is just the basic features of Calibre. Calibre have alot more options and features. It supports the Kindle, the Nook, and other eBook readers.
I'm in the process of adding over 2000 non-DRM .lit books to my Calibre library.
Edit: I'm going to get the new Kindle between now and Dec - more space and being able to read for a month between charges!!
