Syncing Your PDA w/ Obscure O/Ses?

Nomad7674 asks: "I am part of a team helping to build a site for discussing SmartPhones (i.e. combo cell phone and data function devices). We are trying to become a one-stop shop for SmartPhone-related information and have run up against one brick wall that the Slashdot community may be able to help with. We want to document every operating system that can be sync'd with a Palm or PocketPC or Symbian device. We already have information on the biggies (Apple and Windows), on the moderates (Linux and the Unixes) and a few of the more obscure including Amiga and BeOS. But we seem to have exhausted the searches of Google, Alta Vista, etc. and the knowledge of the general community elsewhere. What experiences have other Slashdot readers had with syncing their Palm, PocketPC, or other PDA device with obscure OSes?"
