I finally encountered someone that had a Nintendo DS that I could play around with for awhile. I spent some time playing Super Mario 64 DS and messing around with the other features of the DS. And you know what? I don't like it. It's so awkward to handle. The map on the second screen is handy, but it's not that essential.

I'm probably in my own boat on this one, but that's just what I think about it.
