The Math Pad would hold a number of advantages over graphing calculators. Among them, better display capabilities and the ability to offer a level playing field by ensuring that all students have the same resources at their disposal. As well, they would be less prone to theft as they could be configured to be useless when not connected to the school's server. In summary, the advantages that Math Pads would provide include:
The wedge shape was conceived for ease of storage and ease of incorporation into student desks, if so desired. In practice, the pad would probably need to allow for some angle adjustment on the screen and keyboard to be useful. Worth noting, with respect to pad style devices, is the effort of a U.S. firm to commercialize linux-based pads with handwriting recognition: ProGear 1050HX+
These are much more sophisticated devices than the Math Pad but unfortunately, at $2100.00 U.S., it will be a long time before they are within reach of the educational market.
