My new Timex Datalink can connect to any pc using a USB cable (supplied along with the watch). The watch has build in PIM capabilities. You can upload data into the watch through the bundled software.
The bundled software can only synchronize with Outlook and iCalc. But at office we use Lotus.
Fortunately the bundled software can be extended using plugins. I am in the process of building a plugin that uses the Lotus ODBC driver to get to the lotus db. I will post more info on this as and when available...
