Nobody knows yet what the frequency of corruption in Word 2007 is,
because it's too new.
I've never heard of the document map causing corruption. The Fast
Saves feature and the Revisions feature have been removed from the
program. The Master Document feature is still present, and I'm told
that some work was done to make it more reliable, but I don't have any
data about it.
One thing I find interesting is that the new XML format may make it
easier to recover from some kinds of corruption. Unlike the 97-2003
format, which is a single huge compound OLE container, the XML format
places individual features into separate XML files within the zip
container. If you know which feature is causing corruption, you can
just remove or replace that XML file and reopen the document. You
might have to redo some formatting, but the text of the document
should be intact.
For documents in 97-2003 format that you don't convert to XML, I'd
expect the same frequency of corrupt documents as before.
As an aside, my personal experience is that document corruption is
very rare if you avoid the features that are known offenders. I can
remember only one corrupted document in the last 5 years.
