1.-facebook app, wats the point on having a button that allows you to upload pictures, but you cant have a facebook app like ipod.

2.-Youtube app.- well thats obvious, we really need that.

3.- Message board.- just like Wii, you trade codes, you have friends and you send them messages.

4.-Videochat or voicechat.- well we have a camera and a mic, why not use it like that?

5.-This is not an app, but we should have VC on the dsi, it would be awesome.

I dont put the flash memory, cause i know it very difficult.

If you think that there should be others apps, post them.
