General Information. All Palm OS-based PDA's work across Windows and Macintosh platforms. Here are some of the popular PDA's by Palm and Handspring (the makers of Visor-branded PDA's). FYI, Handspring is a company created by the original inventors of the Palm Pilot. Although we don't have Sony Palm Clie's for you here, they also work with Macs with third-party software conduits.
