I don't know anyone who uses their PS4 to make gameplay videos. On the other hand, I know lots of people who would love the PS4 to gain DLNA streaming capability (the PS3 had it, why not the PS4). Let's focus on the important things first, shall we?
DLNA should be #1. Pretty much every other device in our household can stream from our family NAS bit not the PS4 (which fortunately I won rather than paid for). Stuff we have that does work: 3 * Wintel PC, 2 * Wintel laptop, 4 * Android tablets, 2 * iPhone, 2 * Android phone, PS3, Xbox 360, Popcorn Hour A200, WD Live, Asus O!Play, 2 * Samsung Smart TVs. Stuff that doesn't: PS4, washing machine, fridge, oven etc
