I use Game Notes all the time, probably more then most people, I use them for Highscore sheets when it comes to games that don't save them for example like my Atari Greatest Hits vol 1 and 2 for DS doesnt save highscores for the 2600 games so i always write them down in game notes etc. --- Gotta get em' all, shmupmon!
The game notes would be a lot more helpful if the time to access them wasn't so long.
If you could just hit a button and they would instantly overlay your screen instead of hitting home, waiting, hitting notes, waiting, typing note, waiting, closing note, waiting, resume game, waiting they would get a lot more use.
I used them to write down what enemies I was facing in find Mii so I would not go with 10 heroes just to find out I needed a shadow light combo. --- If I was Rick Astley I would randomly Rick Roll people in the street. Total ownage. PSN: Pratypus
