Datapilot (www.datapilot.com) will let you sync to some of the Palm
series BUT the v600 isn't supported yet. I contacted tech support and
they said that v600 support should be available in the next week or two.
As of yesterday, the v600 was added to their conpatibility list with a
"coming soon" icon so it appears progress is being made.  They told me
that they are releasing version 3.2 and that the v600 will be included.
They already support the v300 and v400 in 3.1.
