Wow, I first responded to this thread eight years ago!
I no longer use Moleskines, or any other paper notebooks.
As many of you know, I suffered a small stroke three years ago that left the right side of my body weakened. I have difficulty writing with a pen or pencil since I am right handed, and my right hand doesn't have the fine motor skills needed to manipulate a pen anymore.
I can still type fairly well on my computer, so now I'm using a software app called Evernote, which is journaling or note-taking software. It works great, and lets me read and update my notes on my computer or my tablet. Adding, deleting, or changing a note on one device automatically syncs to the others. The really cool thing is that I can put the photos I took in each note so I can see the actual images I am writing about!
I keep notes of the dates, locations, and equipment used. When I shoot film, I put that info in, as well.
