My wife bought me a Moleskine notebook a while back, and I love it. It is the hard pocket-sized ruled notebook, and it is perfect for carrying everywhere and taking notes, ideas, drawings, etc.
I have all kinds of variants of the composition notebook, both softcover and hardback, for work, and that's great for work. When I'm on my own, though, I want something smaller. There is a pocket-sized composition notebook, and although I've seen a few friends use it I prefer the Moleskine, as did Leonardo da Vinci, Vincent Van Gogh and Ernest Hemingway!
Still want to learn more about Moleskine? Try The Moleskinerie. I'm like, whoa!

Thanks again, honey!
