A brief compilation of 3DS features.

Hardware

* You can strech the home menu easily.

* Battery life goes from 3 hours to 5 hours with 3D effects applied. The worst case reported by a user was 2:45 hours with full everything (3D, WiFi, Volume, Bright), later the user reported a longer life (something between 5-6 hours) with normal setting, the battery could stand for more than 7 hours accoding to others.

* The system came with half charge. The cradle is quite easy to use.

* Yes you still use friend codes, you only need to put the code one time and your friend will be added to a list It also shows what your friends playing if online, how recently they were online if not, their pick for favorite game

DS games

* DS games are region free so you can play japanese, european or american DS games in any 3DS.

* By default DS games are stretched but you can see it in their oiginal format by pressing Select and Start

* DSiware and 3DS games are region locked.

* Yes you can use the stick in some games. Mario 64 is reported to use it and it's great.

AR Cards

* The AR Games included with the system are: "Fishing on a wall" a fishing game that uses every surface as water, "Graffiti" a 3D drawing application, "Target shoothing", "Mii viewer" wich is an application to select Miiis and take pictures with it,  "AR Shot" a combination of Pool and Golf and an application that let you take pictures with NIntendo characters

*AR cards can be printed free from the Nintendo website. New cards could be released with new games, it's kinda difficult to see these cards sold separately because you can donwload it from the Internet for free.

*Size matter. Depending of the size of the AR cards you can get a much bigger character in your screen, in fact using a card made of 4 sheets of paper (like the one in the picture) could bring a real life size character.

*Some AR characters like the nintendogs have animations while other like the miis only postures.

* Characters react different with every card. So your nintendog could have a kirby, samus or mario hat by just simply putting that card under it.

"later the user reported a longer life (something between 5-6 hours) with normal setting, the battery could stand for more than 7 hours accoding to others."

All I needed to know, and this is perfect for me. 

Decent battery life and I can use the ANALOG STICK!

WOOT! The 3DS starts sounding much better to me now!

Thanks a lot, :D. 3DS keeps sounding better and better. I'm gonna spend hours killing trees to get a monster-sized Mario, :D!

Miis

* You can create Miis easily with the camera or just download them using a code generated by the system.

* Miis are used in the street pass puzzle game, you need new people to get pieces of a puzzle, those puzzles unlock pictures of nintendo characters, the other game is Street Pass Quest, you need help to rescue your Mii and get some extras like hat in the AR games.

* You can't create Miis out of plushies or simple drawings

Camera

* The camera uses MPO and JPEG formats you can actually download 3D pictures from another 3DS and other sources.

* The game that involves the camera is "Face Riders" actually the faces have animations but you need to positionate it in the right place to see the effect. (Creppy Kanye West, Badass Broly)

* In theory you can take 3D video with a future update.

Music

* The stystem store MP3 format

* The music visualizer is quite complete and pretty fun actually.

Booo! Region lock...

Well I guess that's all. BTW some users are comment that the cats from Nintendogs Cats don't listen to their orders, they don't do anything expect eat, sleep, play and do their own things. If you don't give attenton to the cat it's game over even if he/she is not interested in what you have to say.

So yes Nintendo can emulate the AI of a  real cat pretty well. 

This is all from gaf users right?

Youtube, gonintendo reports, GAF and 2chan.

Sounds good so far! are they saying anything about the build quality? does it feel like its worth $250?
