Detecting mobile devices and tablets in 2014

The mobile world changes almost daily. Expanding on http://scottwb.com/blog/2012/02/23/a-better-way-to-add-mobile-pages-to-a-rails-site/ -- which is sorta old -- what do you guys think of this mobile and tablet detection scheme?

Use case: The mobile and desktop versions of my Rails app are very different. Although they share the majority of views, JS and CSS (using media queries where applicable), there are cases where I need mobile-only and desktop-only views, JS and CSS.

Code changes

All tablets should be treated as mobile.
