I'm about to buy Limited Edition of Halo: Reach but I was thinking about our technology, with things like iPad, Netbooks, ebook Readers, etc; why is Dr. Halsey journal made of paper? Why not a futuristic device where she took notes? 
 
Yes, I know, it's a silly question. I guess bungie would have to invent some kind of device for it to be a this-is-how-they-will-take-notes-in-the-future device. So I'm not complaining, I just was thinking about it, maybe it's true and we'll never found a good replacement for paper and pencil.

Because that sounds expensive.

Because, and I quote, "Anything stored electronically, can and will be retrieved electronically" meaning that regardless of how much security she puts in front of it the ONI spooks could get their hands on it and she doesn't want them to. It plays into the whole internal politics going on between the UNSC and ONI. 
 
Edit: Just look at Microsoft hosting Reach on the marketplace, all that security and it still got leaked in less than a day :P Kinda funny that that quote comes from the game in question

There is no match to the feeling of crisp paper in your hands, maybe she shared my love of the smell and texture of a new piece of paper.
