Query: Weak and Warm

For maybe 15 yrs I got by with the free 4-cup conical coffee maker I got as part of a Gevalia promo. When it conked out, I was looking forward to something a little more high-tech. However, the coffee comes out tasting a lot weaker than before with the Mr. Coffee which uses a more cylindrical filter. And the coffee that comes out, even when I pull it out the moment it's done, isn't hot enough! There is no heating element below on the thermal models to keep it warm, and a lot of the heat immediately dissipates into the metal container. But even when I just put my coffee mug underneath and bypass the thermal, it's still not hot enough.Finally, the thermal container could've been designed better so that you have to just tilt it sideways (not upside down!) when you want to pour the last cup of coffee. Next time I'll spend a little extra to get something by krups, braun, etc.
