Prudence--they have something new on the website (I haven't been into the store in too long):

It says the filter comes out for cleaning, but it's not very stylish, is it? And apparently it's only "easy," not "perfect." (eep! and it doesn't fit on their mugs. I wouldn't use their mugs, but still. That seems odd).
I have a Revere-ware kettle on my stove. It's the small size, so it heats pretty fast, and I like to hear a teakettle whistle.
