Tegra To Power Zune?

"Tegra is Nvidia's 1st foray into the mobile computing realm. Nvidia is the company that makes the awesome video cards for your desktops and laptops. Most higher end machines use some type of powerful GPU made by ether Nvidia or ATI. For instance, my Gateway FX laptop uses a GeForce 8800 GTS & my desktop uses a 9800 GTX. Why are GPU’s good for computing? Once again take a look at the laptop. In most laptops the CPU does the heavy lifting for the GPU also, this is called "integrated graphics". In the Gateway FX, a GPU handles the task of blasting pixels to the screen, allowing the CPU focus on more important stuff, like processing and cruching non visual data. A setup like this is called "discreet graphics"."
