I needed it recently. It hard-locked on the PSN Store of all places, I had to hold the power button down to get it to turn off.
I've had issues where my DS4 has desynced if I haven't played with my PS4 in awhile, which forces me to have to do a dumb manual sync.
I often struggle finding the power button on my normal PS4 with the lights on. The symbols are so tiny.
LOL happened to me also several times
This. Whoever thought of that power/eject button design wasn't thinking straight.
Sure, but it shouldn't be needed.
