Our entire IT dept migrated to Vista last week on our primary systems - although each of us has a secondary laptop system. We needed to prepare for the inevitable.. Only had two issues with the logon script - one was a UDF that didn't query memory properly on 64b systems, but not limited to Vista. The other was that the login script ran "behind the scenes", even though we have Run Visible/Run Synchronously GPOs defined. Needed to define a registry key on the workstation to see the script..

Run Logon Script Visible:
Key: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
Value: DelayedDesktopSwitchTimeout
Data: 0
Type: REG_DWORD

So far, very few UAC issues.. <holding_breath>
