title: Why there is a strong trend to use m.* (mobile) sub-domain for non desktop devices instead of using CSS rules to adjust the look of a website?
body: <p>There is a wide range of web capable devices that require different display adjustments, not only mobile phones. Maybe I'm wrong but I think that the m. sub-domain will be the same burden as WWW or http: or :80.</p>
  
  <p>CSS enables us to ensure a proper display in all media, so why are so many publishers and evangelists promoting creating mobile sub-domains?</p>
