What is the point of having KNOX? I'm about to use Odin to root my S4 running 5.0.1, but I'd just like to know, what is the point of KNOX and is it really important? I know it's not just the software I'm not authorized to use, and it'll set my KNOX warranty flag to 0x1 and burn the e-fuse, but I'd just like to reassure myself that I'm not missing out on something here.
Samsung knox is, beside some device hardening, a container or dual persona solution for Android. Think of the knox container as a second completely independent instance of Android running on your phone with own apps, data and settings. It is mostly used by companies to implement bring-your-own-device solutions. However, you can also use it as a private user, but I am not really aware of any great use case for this... so you need to decide whether you want to use the container. I guess the most users can safely ignore it.
