possible 3D mouse, the Essential Reality P5 glove controller? (though navigating any desktop in 3D with icons floating in front of you would need some getting used to.)
also... two-layer DVDs? First of all, Blu-ray IS very high data capacity and all, but to actually shoot movies in 3D... no way. THAT's not gonna happen. All movie theatres would need polarized glasses and special projectors, etc. The infrastructure change is just gonna be too much.
games: yes! though truly 3d games would need beefier graphics cards, since they'd a few more image layers, or who knows, maybe even real voxels, to number crunch.
