Actually, did you attempt to do this with a device that doesn't have a
partnership with the desktop computer already? I just attempted to try to
sync with my ipaq using active sync with the cradle and activesync
attached, but did not do anything else since the screen "do you want to
set up a partnership" was shown on the screen once I unlocked. No data
access was possible.

I think this in itself is not a direct security issue unless the WinCE
device was stolen, or whathaveyou. My understanding of why activesync
works with this behavior is to also allow network synchronization while
the workstation is locked.
