What Nvidia really needed to do was bring out a hand-held where they had licensed the technology from Nintendo, Sega, Sony or Microsoft that would allow people to play their old cartridge-based games (Nintendo and Sega) or their early CD/DVD-Rom games (Sony and Microsoft), kind of like what Sega themselves did 20 years ago with the handheld system that let people play their Genesis cartridges on a hand-held machine.
That type of system would've probably been a better idea.
