My Classmate 1.0

Save paper by using your handheld for your notes, organizing your schedule and storing assignments. I really liked how friendly this application looked when I first lay my stylus to it. Although you can't save information in the trial, I'm sure that any student would love to have this application. You can beam notes to your friends with it or even make a sketch.

A very cool feature is the view/print report feature that lets you keep hard copies of all your work.
