At first, I was really excited about the 3DS, but then I started to really think about it. I've never really liked those "fun" features on the DS series... like Pictochat, pictures and audio on the DSi... sure, they are fun at first, but they get boring fast. I think that it is great to have more depth perception in games, but I don't think I'd enjoy headaches or dizziness (I get those easily after >1 hour of gameplay.) It would be great if nintendo released a portable system that strapped on to your head and directed two separate images to each eye, and had a plugged in controller... the VDS? (virtualboy ftw)
The hard thing about chosing between consoles that you don't have in front of you is, well, you don't have them in front of you to compare. It would be really hard to chose between the Pandora and the 3DS without having them in your hands. It's like asking someone to pick between eating either rice or noodles for the next year and they have never tasted or seen them before.
