I'm using SplashID - started out w/ the program on my iPod Touch and on my VISTA laptop - many options exist; wireless sync works well via the same Wi-Fi network - pleased and would recommend, although I'm sure many others exist - BTW, I installed the iPod version on my iPad (would have cost me extra to get the dedicated iPad app - a little irritating that a 'universal' app was not offered, but $$ is $$, I guess?). Good luck in your choice and please let us know what your research uncovers - may help others - :thumbs:
