According to the Crash: Mind Over Mutant cutscene, N Faux Mercial, the NV can access any file, talk to friends, watch pay-per-view, and shoot julienne fries out of a person's ear from a potato by the device (when Cortex uses this feature they come out of his ear, so when he eats one he spits it out and says it tastes waxy). Cortex mentions that the NV has other features, but he cannot think of them at the time and that it's certainly not an "evil" plan (!) In the DS version they look almost exactly the same as the helmet that Nina used to brainwash Coco.
