On the productivity vein, I've started reading GTD and using the free trial of OmniFocus, which is working really well for me. I like the concept of putting information somewhere that's not in your brain so you can focus on the current context. I tend to waste a lot of time flitting between contexts, so this is very useful. My productivity is already ramping up, or at least it feels that way. I'm not a GTD cult follower yet, but I might get there.
