Your factory warranty will not be voided if you simply root you device. A simple OTA update (say too Kit kat, from approved channels) WILL trip KNOX. My wife's stock 8" got the update through Samsung and the fuse tripped. Those of you bitching about it are going to sure be red when you do update to KitKat and find out its been tripped. I work for a legacy company that only uses secure devices. That's why we have KNOX, its not for a witch hunt to find out who has rooted what and wiggle out of the warranty. Unless you change how the CPU works ( overclocking and such) that can damage the device, that is a different story. But simply rooting without any additional adjustments other than program removal, debloating or changing how buttons work will not void your manufacturers warranty.
This has been bugging me for while.
