I took the download of Express but it does not open on the iPad except to put up a screen promoting OTHER Adobe software for which I have no use.
Beyond that, the iPad won't take downloads from any of the other programs I've tried with the G2 - Apple support person seems to think it's just too old. The Apple "Photo" program does take downloads using the USB adapter from my other (newer) camera so I have ordered a newer camera of the viewfinder type (why I cling to the G2).
