For my part, despite working at it for years, I still don't really like cheap tea (the stuff I could actually afford to drink every day, and that can be found without seeking out rare-in-the-US tea shops or ordering online), though higher-end tea is really good.
We drink a ton of iced tea, but that's easily made on the stovetop in a large pot, and can be bought in gallon-quantities at the grocery store. Having a kettle doesn't improve iced-tea-making very much.
[EDIT] Part of it may be that we drink on-the-go more than other countries. Just a guess, but might be true. Iced tea and coffee (hot or cold) are both much better for that than hot tea—one doesn't usually make a thermos-full of hot tea and drink it straight from the thermos, I'd expect (but maybe I'm wrong?) but that's normal for coffee.
