I have noticed that with drip coffeemakers too. I take milk, not cream, so that adds a substantial amount of cold liquid. Then it's straight into the microwave. Bah!

Percolators are absolutely the best in that category. That coffee comes out of there smokin' hot. And the best by a good length and and a half are the old GE percs from the '60s. They are slow as heck but they make that coffee strong and hot. The modern percs try to speed up the cycle (people are impatient) and as a result they only get half the flavour out of the grounds. Though they can be hacked ...
