I got a mp3 player for Christmas and am hooked on audiobooks. Seriously. I don't even have music on it yet, just books and podcasts. What I love about it is that I can "read" tons of books that I don't have or take the time to read normally.
I just finished The Art of Innovation: Lessons in Creativity from IDEO, America's Leading Design Firm, by Tom Kelley. To be honest when I downloaded it I didn't really know what it was about, the title just caught my eye. But once I got into it and I realized exactly who IDEO is I was hooked! They are in the business of product design, but really consider themselves in the business of innovation. The book is inspiring with ideas and thoughts about how you can bring a culture of innovation to your own business or workplace. Loved it!
