It's possible this distinction may fall away in future (indeed, under certain conditions, even desktop browsers take hints from viewport directives (as is the case with IE/Edge in Windows "metro"/"modern" mode when using split screen view, which picks up on some viewport stuff [don't have the details handy just now]) >> >> The more naive "check for aspect ratio width/height and show a 'resize/tilt' message" situations will affect desktop users as much as mobile/tablet users. >> >> In essence, we'd want to say: let users experience your content/use your site/app regardless of their aspect ratio/orientation, as not everybody can easily change window size/orientation. >> >> Simplest way to achieve this: don't fight the browser; using responsive approaches to then make your content look/work great regardless of orientation/aspect ratio is not necessarily tied to this - it's an optional/extra.
