My wife keeps an agenda file and I keep an agenda file. They are separate agenda files but I keep a copy (an openable backup, in effect) of her agenda in my PDA and she keeps a copy of mine in hers. The machines we use are Psion Revos. Wonderful, but falling to bits now and getting harder and harder to maintain. I don't know of any new PDA which can keep more than one agenda file. Does it exist yet? One with wireless LAN and bluetooth would be fantastic - but only if the software exists for keeping two distinctly separate agenda files. So, an IPAQ, or perhaps a Palm... or maybe a smartphone... Does such software exist out there? Thanks for any help with this. Pip
