The 27-oz Bodum Ibis that Danica linked to is not cordless, but it is
cheap and reliable. One lives on the windowsill next to my computer
table and is in daily use. I hate the idea of plastic and would not
brew with it a home, but I have to say that I've brewed some very
delicate greens in this pot without noticing major problems in taste or
smell.

I too have owned one of these smaller Ibis kettles
(http://preview.tinyurl.com/y6xrqk). They are a good compromise when
storage space matters. I used to travel weekly and I packed one in my
suitcase back then, it sure was a life saver as it is/was hard to get a
proper cup of tea in the average hotel. It served me well and they are
also pretty cheap to boot.
