A Dictaphone, like this Olympus VN-510, should be on every student wish list.
Unfortunately for me, I didn't realize how much easier these devices could make life whilst trying to either keep up with rapidly-talking lecturers, or struggling to stay awake after a heavy night or two.
The Olympus model boasts a 512 MB memory, and lets you store up to 300 hours of digital voice recordings. It also works for up to 39 hours on a single battery charge.
