What a marroon .... LOL That article's author doesn't even have his facts straight. Even more frightening that nobody in the flame war comments attached to the article pointed out the BS.

"... Sources said the system's graphics card identifies itself as an Intel Graphics Media Accelerator 900 (GMA 900). Some other reports have placed an Intel Graphics Media Accelerator 800 (GMA 800) inside the units ... "
