IMHO, I thought the review was rather shallow. He could have spoken more about the expansion, add-ons, variants, kinds of video outputs, etc. If he really wanted to go for the gold, he would have opened up the TG16 and PC Engine to compare the insides to see why one is bigger than the other.
But I do realize the PC engine was on loan. But that's so lame, because given his popularity there is no real excuse for not picking one up for his own review.
