If I am not mistaken I think you mentioned that you had purchased a Keurig
(or similar) single cup coffee maker.

I have a question. Can you (or should you) just leave it "on" all the time
so the heater has preheated the next cup's water? Or do you regularly turn
it off when not in use?

I finally got around to getting one. I am slowly trying the different
coffees from the various brands that came in the sampler box.

So far, Green Mountain Nantucket Blend seems to be my preference, but I've
got many more to try.

The hot chocolate is pretty good also.
