Legal pad. I've tried tons of different software options but never used them and never reacted in the way I needed to. Plus any cloud based solutions of logging into things just adds more cognitive overheard. Often times I'm jotting notes down or like to draw little diagrams or use some other reasoning for emphasis. I feel by writing things down I remember it better. There is also something very special about hand-writing the date everyday (well, work day at least).

If I need it to be multiple places and accessed by a computer I'll use the basic notes app from apple that I can open up on my phone as well.

For a more complete answer I really like using gitbooks to write my own version of tutorials or documentation. It's a nice bit of software to organizes pages and markdown is fun.

I hadn't tried gitbooks, thanks!

It's really beautiful, probably one of the more enjoyable web applications I've used. Plus you can share with your friends and because it's git you see that history which is neat!
