The Franklin product I always wanted but never had was the REX. This was what PCMCIA slots were made for, a mini-organiser that was just cool in pre-iphone times, when any other organiser/PDA needed to be plugged in with some very slow cable.
Citizen made the REX and they sold it on to Xircom, so it wasn't as if Franklin did much apart from to add their peculiar style of marketing to it.
