I'm a college student in a class where powerpoint handouts are common. What I'd like to do with an app is scan the powerpoint into whatever app is out there and be able to take handwritten notes on the scan directly on my ipad2. If possible I'd also like to record the lecture audibly without the profesoor knowing I'm recording. Is all of this possible with one app? I see some scanner apps, but I don't know if they allow a user to do handwritten notes. Basically in a nut shell, what would you recommend to a newbie who is looking to rid himself of notebooks? Thanks in advance!
