A very simple class that takes in a user agent string and returns the browser name (Firefox, Chrome, Opera, etc.) and also the Operating System (Mac, Windows, Android, etc.).
Firstly, you should not use browser sniffing for fearture detection, use Modernizr.
We mainly use this for style tweaks between different browsers. Or sometimes you may need to add a little script (differences in keystroke handling can be difficult to feature detect) or tweak on a specific platform combination and so you might do a check to see if that makes sense.
The results are pretty crude. We only return internet-explorer if any verison of IE is found. There is no version information.
For the platform, we only return that operation system. This means all iOS devices (iPad, iPhone, iPod) would only return ios.
If you need to know specifics about the device, use media queries.
