At my company, we used to use IPv6 internally and IPv4 publicly for future proofing and easier migration to a all IPv6 environment. Instead of changing the entire infrastructure we just had to change the gateway.
I have a couple of 4k LEDs in my kitchen, but also have much warmer LEDs in other places around my house. The reason the kitchen is different is so it feels sterile and clean. The cooler light gives this appearance more than warmer light. I guess the same reason many places have white counter tops.
Not sure if you're interested, but I've got a couple of my lights hooked up with Google Now so I can say "Ok Google, turn the living room lamp on" and also when I connect to my wifi network and the sun has set it'll turn my living room lamp on.
I don't understand your complaint. Out of all the articles I've read lately this page seems to be easiest to read. It focuses on just the content and formats it well.
