Some systems already have that. Replaced a switch yesterday and re-arranged some things on my network board and got a HomeKit notification that some things were offline and when it came back. Knowing when something goes offline isn’t as useful as keeping things up though. With something like a hardwired camera/NVR, even if your ISP service is interrupted the cameras can still record, and you can put a UPS there to keep things going, even if the rest of the network is down.

I’m sure there’s applications where that’s true, but then you’re essentially talking about having a gas furnace plus a heat pump, so you’re installation cost is close to the sum of both systems. Energy rates vary by region, but around here electricity is about 7 times the cost of gas, so a heat pump running at a coefficient of performance around 3 would still cost twice as much to run as a natural gas furnace, it would be cheaper to just turn off the heat pump altogether and only use that “supplementary” heat.

I suppose if electric heat is the primary option then sure. Around here though natural gas is pretty much ubiquitous and the cost per joule is a heck of a lot lower than electricity. About $6/GJ for natural gas, compared to about $42/GJ for electricity. Would need a pretty efficient heat pump to see the cost savings in my area.

Could be a larger demographic thing. Tech enthusiasts tend to have lots of devices(tablets, portable computers, etc.), so they tend to like the smaller form factor phones since they can always use their tablet/laptop when the small phone is limiting. Those people are also the ones you see in these kinds of online communities. For a lot of other people though, they’re getting the big phone and then not having a personal tablet/portable computer at all. Those aren’t the kind of people that hang out online and talk about tech stuff though.

Also agreed. However the manufacturers know how many of each device they sell and seem to think the smaller form factor devices aren’t very popular. I imagine there’s multiple reasons, like the smaller phones tend to also have lower battery life and lack other features due to size and they tend to appeal to people on tighter budgets that upgrade less often.

Something kind of unique about UnRaid is the JBOD plus parity array. With this you can keep most disks spun down while only the actively read/written disks need to be spun up. Combine with an SSD cache for your dockers/databases/recent data and UnRaid will put a lot less hours(heat, vibration) on your disks than any raid equivalent system that requires the whole array to be spun up for any disk activity. Performance won’t be as high as comparably sized RAID type arrays, but as bulk network storage for backups, media libraries, etc. it’s still plenty fast enough.
