My desktop, laptops, and phone are basically always on (albeit usually asleep or closed) unless I'm doing a restart for some reason. Thinking about it now, this may not be the wisest decision, considering how much my desktop cost (it's a 5K iMac), and I absolutely do not have the means to replace it anytime soon. I may start shutting down every night, even if just for superstitious safe feelings.
My PS4 is often on, because I play it nearly everyday, and when it's not being played, my GF uses it for Netflix and Crunchyroll all the time. Otherwise I keep it on suspend mode.
