I rather like tea, but it's just so awkward. You start off with the tea bag in the hot water, and – then what? Do you pay attention and take the tea bag out after a certain time? What do you do with it afterwards? What about cream and sugar – do you put that in right away, or do you have to hang around and wait until you take the tea bag out? It's all much more convenient if you have it sitting there steeping in a separate kettle, but then you need to have that separate kettle sitting there, and – ugh.
Tea doesn't have to be complicated. Boil some water, turn it off, set some tea bags in it and let them soak for 30 mins to an hour. Get a gallon or half gallon pitcher, pour in a cup of sugar for a gallon of tea, pour in the water that the bags soaked in, ring the rest of the water from the bags out into the pitcher, stir, chill/drink. Making it a cup at a time just seems siliy when you can make a whole gallon and throw it in the fridge.
Coffee has none of this confusion and is stronger anyway.
Depends on how many bags you use and what type of tea it is. I suppose you can make it as strong as you want.
