I inherited a Dualit toaster. It's over 25 years old, will withstand nuclear attacks come WWIII, and can be broken down to mod weapons in Fallout 4. In short, it's the pinnacle of toasting technology.
Kettles are a bit more difficult. Steam is incredibly corrosive, and will break down plastic (possibly in combination with UV), and any sort of weld on the spout electrolytically corrodes.
The best combination seems to be a kettle where the spout is pressed stainless steel as part of the body.
Now this planned obsolescence smart gadget bullshit needs to stay out of the kitchen. In fact, fuck the free market; anything with an iPhone dock needs to be banned.
