I'm a bit bummed regarding the handheld version of 20Q. While I was in CompUSA the damn thing guessed 'porcelain tile' correctly. Impressed I payed the $15 since it'd make a neat stocking stuffer. Well, a friend stumped it tonight with 'iron' and 'watch'. >:(
though it says it'll guess what your'e thinking in 20 questions it really takes liberties with the first question since you need to specify whether it's an animal, vegetable, mineral, other or unkown.
