Nintendo DSi/3DS
 

What is the difference between a DSi and a 3DS other than the 3D function?

here, you can read the list of features here.

keep in mind that this is an older article and I think they added more features since then.

the wikipedia article is a bit better actually

http://en.wikipedia.org/wiki/Nintendo_3DS

Cheers man. I did a bit of research into it and from the looks of it added 3D and improved graphics is the only difference.

what? did you even read the wiki article? lol

there is this counter that when you walk it gives you credits/rewards depending on how far you walk.

Do they already have that for DSi?

Yeah I skimmed the article, but I mean useful things like memory storage/webcam. Step counter is a bit pointless, considering I'll probably only ever max out 5 on it.

In addition to that 3Ds has a motion sensor and gyro sensor

cool. What is a gyro sensor, something to do with movement as well?

That's all it is really. It senses movement :)

They should have included a GBA port I think man. Although I suppose they'll probably put a virtual console up for download.

It's called an emulator.
It's not legal but it is very nice :)
