If there's one thing Nvidia brings to the table, it's the ability to bring power to mobile platforms. Just look at the Ion (for Atom-based systems) and the Tegra (for mobile devices like the Zune). Both bring H.264 hardware acceleration and and the potential for light gaming to traditionally weak mobile platforms. While I will admit that Microsoft still has some work to do to improve the experience of gaming on the Zune, it has potential to truly bring the Xbox360 a companion mobile gaming device (and mend their relationship with Nvidia along the way).

I really enjoy the reviews that are done by the "Angry Video Game Nerd" aka James Rolfe. His angry rants are both stylish and nostalgic. He is out with a new video this week. It is actually the third in his Castlevania series where he goes over games for the Super Nintendo and N64. If you have never seen a video by the AVGN, it's definitely worth checking out if you are an old school gaming fan. Feel free to skip it if you're not. One more thing...the Nerd gets pretty angry and that does not stop the colorful words from coming out of his windpipe...so NSFW (Not safe for work).
