Yes. Although you can't really 'make' videos, you can take pictures and record videos with the Nintendo 3DS
Yes
yes
unfortunately, no
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 :)
its roumered that it will (hopefully)
no but there might be a update in July
You can't :(
No. The 3DS does not have the processing power to access YouTube, Vevo, Fuse.tv, or any other websites that have music videos, let alone even play a video at all. It's just not what the 3DS is meant for.
Yes it can play videos. You can`t play e-books
it has 3 cameras for fotos and videos
Yeah, but I don't have a 3DS, I saw it on a few videos.
