Some people have reported light bleeding around the edges of the display, the pen input seeming to be off a few millimeters, creaking on one side or the other and some get really warm on the back during multitasking. MIne has none of these lol. I would also connect it to a bluetooth keyboard and make sure you don't have the disconnect problem that was initially prevalent. I think it has been less common with newer units though so samsung must have caught the problem eventually. I use many similar apps between my phone and tablet. The great thing about an android tablet it that it can even sideload apps that are designed only for phones meaning you have about 1 million or so to choose from. Screw the Ipads 475,000 lol. I run gmd gesture and spen control and tasker as must haves. I would recommend getting note buddy, secure settings, and external keyboard helper pro as well. I automate mine to turn on my bluetooth and connect to my touchpad anytime my usb keyboard connects to the tablet. and removing the spen using the note buddy plugin changes pauses and unpauses gmd gesture control so It doesn't interfere with writing or drawing. Spen board switcher is also nice to set your imei to change depending on insertion or removal of the spen. stylus beta is faster and more accurate than the samsung keyboard that is based on it. I use nova since touchwiz is a pain to me and i use the 4 window multiwindow mod. Multiwindow manager xposed modules and the one to make any app multiwindow are all musts as well as penwindow manager and pen window launcher. Using gmd spen and gesture you can actually launch penwindow at any time using a simple finger or pen gesture you set up without going into air command. Basically though any android app should run.
Oh and yes knox still gets tripped but if you bought and accidental protection plan its still worth rooting in my opinion especially with cleanrom 2.0r2
