I'm a tea drinker, but I don't have an electric kettle. I use a stovetop kettle. If, for some reason, I am going to be drinking tea throughout the day, I make an entire pot, strain it (I always use loose tea, not bags) and put the tea in the refrigerator to be heated a cup at a time in the microwave.
Mr. Nutrax uses a regualr coffeemaker.
Otherwise, I don't know what I'd so with one. I rarely have need for a small amount of boiling water. It's usually a pot for cooking pasta (I'd need a very large kettle for that) or making rice. If I need a small amount, I use a microwave. I don't do things like instant oatmeal/porridge (ugh!) or instant soup.
I've used hotel electric kettles when traveling in Australia & New Zealand. Much better than having to heat water for tea in the hotel coffeemaker, which never gets it hot enough & is always contaminated with enough coffee oil to make the tea terrible.
Incidentally, I have no idea how to use a coffee maker.
If it's not some fancy things, it's put coffee in basket, put basket in coffeemaker, fill pot with water, dump water into coffeemaker, put pot o burner, turn on.
