NVIDIA is working hard to make good on their promise to make $199.99 Tegra 3 quad-core tablets possible. NVIDIA's VP of Investor Relations, Rob Csongor recently revealed during a recent stockholder meeting that the company is working on what it calls the "Kai" platform. He didn't go into detail about it, but indicated that it will be a low-cost architecture that will allow for budget priced quad-core tablets. The stockholder meeting is pretty long at about 33 minutes, but we have included it in the source links below. Here's a quote from the audio:
Our strategy on Android is simply to enable quad-core tablets running Android Ice Cream Sandwich to be developed and brought out to market at the $199 price point, and the way we do that is a platform we've developed called Kai. So this uses a lot of the secret sauce that's inside Tegra 3 to allow you to develop a tablet at a much lower cost, by using a lot of innovation that we've developed to reduce the power that's used by the display and use lower cost components within the tablet.
