Serious? Weird. I bet you'd struggle to find any other type here. (OK, maybe not strugle, since 40% of the population has no electricity, but every shop has electric kettles in a bewildering array of variety.)
...so since I'm heating up an element either way, the point is probably moot.
Well, the kettle is much more energy efficient. Instead of heating the element, which heats the kettle, which heats the water, it just heats the water directly. Faster too. Especially if, as I do, you only put in enough water for the cup you're making.
As for this:

Then they did the same thing to plain tap water and dropped a spoon in...but this time, on contact the boiling water exploded out from the cup. I don't recall the Mythbusters' exact explanation for this occurrence, but it had something to do with the fact that the tap water contained impurities.
From what I remember reading about this, the issue is the container, not the water. If there aren't imperfections in the surface where the bubbles from boiling water can form, the water gets super-heated. Heated above its boiling point, and when it's disturbed, like by putting a spoon in, it can "explode." Having the teabag in there would reduce the possibility which is rare ayway.
Hold on...
Microwave Boiled Water Can Explode
Impurities actually make it
less dangerous by providing nucleation sites. (As your teabag would.)
But let me just interject that I find Alynna's process to be truly abominable in terms of tea-making. Boiling a cup of water with the teabag already in it...urg. Stick to coffee you guys.
