Several websites have been following the rumor, that started at donanimhaber.com, but apparently no one can confirm whether or not Microsoft's latest portable media player does indeed use NVIDIA's system-on-a-chip design.

Well PC Perspective can: the Zune HD does in fact use NVIDIA's Tegra processor. I actually learned this fact from some NVIDIA staffers over at Computex in early June but I guess I just didn't realize how "news worthy" the information was. No longer do you have to worry about "rumors" on the subject - Tegra has its first major design win.
