Smartglass integration in campaign

So reading a little about how Dead Rising 3 is going to use Smart Glass and sounds actually kind of cool. In terms of Halo’s campaign I would like to see some integration… I remember Halo 4 was supposed to have something that apparently never materialized outside of just a MM stats app.

I was thinking something like a personal data pad filled with info on various enemies, weapons, etc… You would and do encounter through out the game to give some context to the universe and such. Kind of like the scan feature on halo anniversary.

Other ideas?
