I think I don't see how it'd really save that much time/that many steps.
If you have to go fetch water and coffee, and potentially milk, and then not only put, say, milk back but also bring the coffee pot and/or filter to wash and then return and toss the grounds from the kitchen to wherever and back, seems more trouble than just getting up for more coffee.
I suppose if it was one of the pod things it's only a matter of fetching water and potentially milk or what have you and then bringing it back. I dunno, is it that big a difference? Good to stretch?
