The constant high current draw on the laptop is probably the heater that keeps your knees warm.
Multi GB memory sticks are happening and mechanical disks will become redundant in portables. It won't be long before you can capture hours of hi res digital imaging in real time to solid state chips. Archaic power hungry mechanical storage will be relegated to the museums of the industrial revolution.
IMHO (not that I was ever humble) eventually solid state will replace everything that is round and stores data, but the cpu will stay cool as long as your knees need warming
