I’ll admit: I don’t give Newton-to-Windows syncing its proper attention because I don’t have a XP/Vista PC to try it out.
But there is an NCX/NewtSync-like program out there called Newton Connection Tools that will help Windows users connect their MessagePad with a modern version of Microsoft’s OS. NCT helps with all the usual sync needs, like package installation, data backup, and Microsoft Outlook syncing, plus Newton Protocol tools that allow for further Newton software development. Pretty cool stuff for the Windows crowd.
