An invaluable tool for lectures, the Echo lets you listen back to exactly what the lecturer was saying while you were jotting down a specific note (or drawing a particular doodle).

Price of entry is steep, but if you rely on lecture notes a lot, it's simply essential and – aside from a portable PC – one of the best student tools around. Just remember you'll need to buy the recording headset if you can't sit close enough to your subject.
