Depends on the price Nintendo suggests (knowing them, it will be enough cheap)

If Nintendo allows people to watch movies, video clips and listen to music, then we have a winner here.

Some info of interest:

If the DSi can do this with software alone, I can't imagen what the hardware of the 3DS will do combined with software.

If I can only find the link, but rumors are the 3DS will have in between GameCube/Wii and Xbox graphics.

In my opinion the 3DS will be more successful than PS3-D for a reason,

1) the 3DS will not require 3d glasses neither a 3d capable TV

2) not evey PS3 owner will upgrade to a 3DTV yet when they just upgraded to their still new HDTV's 

3) 3d glasses bought separately ..

3DS will be huge because it is taking the "new" factor out of Sony's venture into 3D. It is also a far cheaper and more convenient alternative to Sony's angle, which requires a $2000 investment and wearing 3D glasses just to get the experience. Why go through the trouble of that when you can get the same experience on a handheld for $200?

I am intrigued to see what additional features the 3DS has as well (video playback, whatnot). What other applications do you think Nintendo will/should have on the device?
