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). No longer will you frantically have to write down everything; now you can just play it back in stereo by pressing the pen to your headlines. Quite frankly, despite its involved setup and the requirement to buy special paper, it's ingenious and revolutionary. 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.
