I don't use a notebook anymore. Now I start with a small document containing what need the project is supposed to solve, some design notes, and I use omniGraffle to sketch out diagrams. One tip: I save copies of all of my "idea diagrams" in a folder and I often start by grabbing an old file and copying parts of it. I find that using a diagramming tool is almost as fast as sketching with pencil and paper.

I also rely on Evernote (happy paying customer) for storing resources, random thoughts, photos taken with my cellphone of receipts, etc. I don't use Evernote for project materials however, just general resources and a history of what I have found interesting and useful.
