title: Is there a quintessential mobile User-Agent regexp pattern?
body: <p>There are endless examples in the tubes of regexp patterns designed to detect mobile User-Agents, even quite a few in answers herein. Do you know of one that is perhaps most widely used and supported (updated, in perhaps a Git repository)? There tends to be a <code>It's dangerous to go alone! Take this.</code> version of everything, eventually (e.g. <a href="https://stackoverflow.com/questions/116754/best-css-reset">browser reset CSS by Eric Meyer</a>, et al), so perhaps there is for this as well.</p>
