About me: I am a chemical engineering student. I'll be taking - Physical Chemistry - Statistics - Transport Phenomena - Analytical Biology next year. I currently have a Macbook Pro 13" and an Iphone 5. I am willing to buy another product or software for school. What I need: After reading comments about my professors I've discovered most of them post online notes (I'm guessing powerpoints) which they use to teach class, most students print them or only annotate the important points on a notebook, I've seen some write on their laptop or notepad. I'm trying to find the most efficient way to take notes. I also commute to school so I'd like to carry less notes to class. Some ideas: Buy a Notepad or an Ipad and write notes directly on the powerpoints Cons: Smaller than a notebook, and not sure how well notes would look (equations, graphs etc.) Pros: Easier to draw an equation or graph Write on the powerpoints on my Macbook Cons: Would have to find an efficient way to write equations, plots and notes to the lecture notes, I do not like the keyboard sound on a silent classroom, would have to work on my typing skills Pros: Bigger screen, LiveScribe http://www.livescribe.com/en-us/ If you have any other suggestions or experiences you'd like to share please do. I am relatively new to the apple family, and so far I am greatly impressed. I want to make the most out of my apple products in school and take good notes as an engineering student.
