I spent 10 hours in the game to come to the conclusion that OOT is amazing but that I won't be able to fully appreciate it by playing it 'handheld' on the 3DS. The immersion doesn't quite work for me, especially in the dungeons where I find the game's readability difficult on such a small screen. I imagine that if you've played the original, playing it in handheld mode is a pleasant extension of the experience, a way to rediscover it. In my case, I would just like to experience it in a way close to the original experience (if such a thing exists). Like a good snob, I think I'll play it on the original hardware at 20 fps.
