Sorry folks, mobile devices deserve completely differently designed websites than normal sites. No amount of style switching is going to change the fact that it’s a completely different experience. Different experiences deserve different design. Period.

He’s right. Note that this isn’t just good design sense, it’s also a practical take on how to build them. It fixes any issues one might have with the mobile design of ones website, as designers can just let it go. Simply let the UA (User Agent; the browser) decide what’s best for that device with those fonts and those dimensions.
