Absolutely correct. A steel one would be a casting with varied thicknesses throughout and that can definitely change shape under the temperature extremes you get there.
Guess on your next trip you could bring back a granite surface plate as a lap top desk. Gee its only an 18 + hr flight from the US to Australia. Once your legs went numb you wouldn't notice a thing.
