Now that I have read the instructions and started to use the vault, I find that I see the Vault as a real improvement, at least for my implementation.
The file manipulation and structure is just like Windows, the fact that the folders are "virtual" reduces the possibility of duplicate named files hiding in multiple folders.
Once you get used to navigating in the Vault I bet you become a believer.
I had some transfer issues but they were easily overcome.
Make sure you have a good backup and I found that doing a migration from the respository to a Windows file system gave me an easy way to fix any migration problems that I encountered mograting from Repository to Vault.
