To be honest I think the bearing is very indirect, if there is any 
bearing at all. Small to medium Office documents as are the target of 
these applications are the poster child of document types that should be 
expressed in XML, and the fact that they weren't already was an 
anachronism that I'm sure I'm not the only one to celebrate the 
progressive death of.

I am not in the least surprised that zipping Office XML documents makes 
them slower than the binary formats they used to be encoded in. In fact, 
given even superficial knowledge of said binary format, I would have 
been shocked if that weren't the case. To be kind, it simply wasn't very 
good, and it's common lore that the people in charge of the Office file 
formats at Microsoft don't know what some parts of the formats are there 

I don't think we need to crowd the issue with a mention of the many XML 
formats that are happily in XML and use generic compression when needed :)
