I recently put together a setup that some might find useful. It would certainly work well with Rands' system. I bought some flexible whiteboard foamboard, cut it into 2" x 6" pieces and hot-glued magnets to the back of them. I jot tasks down on each one, and stick them to the metal casing of the cabinet by my desk. These can float up and down in 'priority', left and right into 'long term / short term', or however you want to move them. The beauty is simply that you can use their position to give meaning, without having to re-write them all the time.
