For me the perfect kettle is a simple glass kettle because I've found that it doesn't change the taste of water whereas metal or plastic kettles do. Also, I don't like the idea of heated plastic compounds leaching into my water.
Bonus, it looks cool to see the water start to form bubbles and then to go into a full on boil!
I challenge you to a blind trial. I very much suspect that using an electric kettle and a glass kettle you would not be able to taste the difference of the water once cooled. (We'll run the electric kettle twice with clean water followed by a flush, as most manuals state.

I don't like the idea to getting burned on my kettle. So if anyone is looking for a kettle that should be metal, invest in one with double walls if you want it for the "look" or one that has palstic outside if you want it for the "taste". Having cheap metal kettle is much worse than having even cheaper plastic one in my opinion.
