i know nothing of the technical aspects but i do know that there are very many different calculators and graphing calculators, including simulations by hp and TI of some of their older machines, as well as hp and TI machine emulations by third parties, that are perfect replicas of the originals , some with nice improvements, and they calculate, compute, and graph amazingly well.
my point remains, J guides could be turned into Apps for free or money to be given away or sold by i tunes. i like to think that J can some day be an i pod touch... App, and should be, as these machines are more sophisticated, friendly and reliable than the pocket pc's. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
