I would like to be able to use an iPad at college for class notes and drawings. As well as this while im jotting the lesson is being recorded with the built in mic or a bluetooth one. It would be nice to be able to group the notes to a Lesson name say 'Maths', 'IT' so you can have more than one and then the dates with a title of your choice (Lesson name). The ability to export the notes as an image and the recorded lesson for review. This would then allow me to stop using paper in class and if I miss what the teacher said I can review with the recorded audio. Does that sound any good. MD
