I now have that nifty cup and the filter is waay better than I thought it would be. It has an annoying tendency to keep just a teaspoon or two of filtered, good tea still in the cup after it's released the majority of its load; but it more than makes up for that by being microwavable (the coffee urn water is NEVER hot enough for tea) and dishwasherable (is that a word?). Plus it's just cool to watch it work and the tea I get out of it is much hotter than the tea I get when I use a teabag in an open mug.
Happiness is loose leaf tea that's dead simple to brew and wash up after at work.
Okay okay... I'd have to open a coffee roasting house and a tea house in one and actually pay both the amount of attention they deserve.
