I live in the Yukon, and get out and about in -40 regularly. I've had hypothermia a couple of times, and it's not particularly nice. I imagine at some point you stop feeling, but everything before that isn't nice.
I've talked to someone that claimed to have had severe hypothermia, and he said that there was a sense of euphoria (after a certain point).
Also, I know that after a certain point people suffering from hypothermia start feeling hot and start stripping off clothes (and promptly freeze to death).
Agreed. Was out on a frozen lake last Christmas, and realized that the sun had gone down and I'd pushed too far before turning back. The scenery was starkly beautiful, but I just remember thinking -- I could be dead in an hour, within view of all of these cottages. Not a pleasant thought.
