No one replied to my post but I went ahead and bought it anyway. I haven't had time to use it a lot, but I did import one of my trees from Ancestry.com so I might can (and will be happy to) answer questions for you.
My import seems to be intact. Names, dates, places are all there. The sources are there but only the name of the source and the link. The actual source document did not import. For example, say that John Smith was born in New York, NY in 1900. Next to his name and birth date, there is a subscript number that is also listed in the source section. You can click on it next to his name and it will take you to the source section where it says, "1900 US Federal Census" and in the details section it lists the city, county and state. However, you can't view the census record. That has to be copied separately from Ancestry.com and then placed in the picture file of Reunion. I use iPhoto for this and it's drag and drop, very easy.
I hope this helps you. If you have any other questions, please feel free to ask!
