I don't mean to spam, and I'm admittedly very biased, but my product Zen (http://agilezen.com/ http://agilezen.com/), helps me stay organized and makes me much more productive and happy. I always have a million things to do, and Zen stops me from being overwhelmed. (That's why I wrote it!) On a less self-serving note, I'd also suggest (at least) two monitors, a good keyboard, and a good desk chair. Fatigue, RSI, and task-switching are all very real productivity drains.
