Pocket Mirror or Keysuite
I have been using Keysuite for years. I have an old Palm Tungsten E2 & sync Outlook at work with Exchange (Windows XP Pro) & at home with Outlook.pst. When I went to Windows 7 I was disappointed that there was no more USB support, but with a Targus Bluetooth Adapter for my laptop & desktop at home I found syncing was buisness as usual. I did have conflicts, so I just have 'work' overwrite Palm & Palm overwrite 'home'. I find it to be the best solution. Having the unlimited categories is good too. I recall using PocketMirror years ago.
Sorry I couldn't provide a complete answer, but a little feedback on my experience may help this thread.
