A couple of weeks ago, I wrote about my unexpected love affair with my Kindle. "No more books!" I vowed. It was a whirlwind romance, and now it seems that I've come to my senses: I miss paper. There are a couple of books I've been looking forward to reading -- authors I'm really excited to devour -- but when I think about consuming them on my Kindle, it's like...cold mashed potatoes. I can still put my Kindle to good use, but my heart belongs to the book. Why am I so surprised?
