It's very probable that a "mobile" or "tablet" screen will be zoomed in

This assumes that the entire page is onscreen at once, which is a pretty 
bad assumption for said scenarios.

I feel like I must be missing something pretty fundamental here.  Either 
said "people" are assuming users never use zoom-and-pan type controls on 
their devices or there's something more complicated going on.  What am I

Sure.  I'm not entirely sure how sympathetic I am to the need to produce 
"reduced-functionality" pages...  The examples I've encountered have
