This issue was added for the FPWD:

"ISSUE 1 in the current ED "dbaron: The question is, what does this do on  
the desktop browser? (And what's a desktop browser)"."


Perhaps the term "desktop browser" is misleading. Currently the term is  
used in the Introduction and in the UA stylesheets sections. "desktop  
browser" in this context is a browser with an initial viewport width  
greater than a certain width (Something similar said in section 13 UA  
stylesheets).

A desktop browser should typically not need to have any UA styles. All  
@viewport descriptors set to their initial values yields an actual  
viewport equal to the initial viewport, so that should be fine.

So what happens if a document with @viewport styles is shown in a "desktop  
browser"? Basically the same as in a small screen browser modulo the UA  
styles. One difference could be that between browsers which have  
magnifying-glass type zoom and those who don't. The Conformance section  
says a UA still can conform without support for actually changing the zoom  
factor.
