As of yet, there is no dedicated video chat application for the 3DS. Video chat is still possible if you, say, use the video chat feature in Pokemon Black and White Versions.
The 3DS has no video-out, therefore there are no video cords or cables for it.
Yes, I do it all the time! Just use the internet browser. Works really well compared to most web sites.
The 3DS does not support the DSiWare Flipnote Studio. In regard to that, no, the 3DS does not have hatena.
That depends, what video are you talking about?
the 3ds will take video in an update coming in May some time. REMEMBER TO UPDATE EVERYDAY.
there is no puss in boots the video game in the 3ds
No.
The 3DS currently does not have support for Adobe Flash Player.
The face on the 3DS is not pictochat, as the 3DS does not support it. The face is the Friend List where you can register other player's 3DS via Friend Codes.
There is no easy way to do this. The 3DS does not have a video-out port, so there is no way to connect 3DS to a TV to display its video on the screen. Instead, you need a capture card, and this card must be installed inside the 3DS, spliced into the circuitry, with a hole cut in the case for its USB port. This port can then be connected to a monitor to stream the 3DS's video data.
You can download the Youtube application from the eShop if you want to watch Youtube videos, you can not watch video files such as mp4s, but if you upload them to Youtube you will be able to watch them :)
