Q:goodreads(.)com is quite nice to keep track of your reading. I've had a Kindle for almost two years now. I love it for reading academic papers but haven't read a 'fun' book on it yet. I'm not sure if I'll like it. Do you still feel attached to holding a physical book? I probably should get a few Kindle books for when I'm traveling, it would be much easier.
I’ve used goodreads some, more to suggest new books to read than keeping track of ones I have already read. I still like holding actual books, but mostly I just like using the kindle! It’s so much lighter and easier to carry around (put in my purse!) than an actual book. I bring it with me everywhere and find myself reading whenever I have even a few minutes to myself. The only reason I really still read actual books is because I worked at a Borders and have literally over 100 I have yet to read. I probably won’t buy any more physical books.
