Maybe something here will help you.
Having the mini DVI to VGA adapter, is also a good thing to have as 98% of hotel, convention centers, and other popular places that presentations still have the VGA input that will not accept the high quality input that Thunderbolt provides, they are mostly in older Windows world, as that is the majority of how their presentations are presented to them to project.
I hope this gives you some help.
All the best
