The PSP let us watch movies on memory cards. Aparently nintendo thought that was a cool, yet limited, idea.

On the Wii, you'll be able to view photos/movies on an sd memory card via the wii, plus oyu'll be able to edit & save them. All with a 3d positional sensative remote control! Will we be able to e-mail them to other people? Not sure, but tat would be pretty cool (it aparently already supports using the web. This could replace webtv for many. It would even add features like the pictures/movies)
When vegas getting THIS feature!?
