Not satire at all actually, and to be a counter movement would suggest that there was more movement behind PDAs than there actually was. The name maybe a little bit of a joke, but this was a legitimate system that Merlin Mann came up with and used in his job at the time that served functionally the same role as a PDA at a fraction of the cost. About the only things it wouldn’t do is synchronize with your computer or tell you the time; but it also didn’t run on batteries or depend on an idiosyncratic pen input method or tiny keyboard.
