The biggest advantage I've seen to having my Kindle is that it stops people asking me about the books I'm reading while I'm in public. When I would sit on a bench at the park or grab breakfast at my local diner I'd always get questions about what I was reading and running commentary from random strangers about my choices of reading material.

Now that I have my Kindle with me I get the occasional question about the device itself but for the most part I'm left to read in peace, which is all I really wanted. When I'm home, though, I still go for a book.
