re boiling water : as most real tea drinkers know, you should not boil water when making tea - it makes the water "flat" and affects negatively the taste of the brew, just bring the water up to nearly boiling (no jokes please about whether tea tastes of anything anyway ... I'm English).
And you don't boil water for making coffee either.
Up until about 18 months ago, we used a plastic cordless electric jug to boil our water but it finally died after 15 years of service.
It got replaced by a cordless stainless steel version...it died last week.
Screw what it's made of, just give me something that lasts as long as the plastic one.
The plastic one was more efficient also since the element was in the water, (direct heat transfer), and not heating up the base as in metal versions, (indirect transfer).
Yep, still a tech, give me something that's efficient, does the job and lasts a long time.
