VISTA sux. I sync with a vista pc and an xp pc and have no troubles with xp but vista is a pain in the ***. I think it has something to do with their desire to keep pirated stuff in check. I find that using the microsoft activesync craps out on vista and using the windows mobile device center ap is less buggy. See this link:
