Businessweek: "Apple won a sweeping legal victory against Macintosh clone maker Psystar Corp. Nov. 13 when a federal judge in San Francisco ruled that Psystar had violated Apple's copyright and the Digital Millennium Copyright Act. Judge William Alsup struck what may be a death blow for Psystar by granting Apple's motion for summary judgment while denying Psystar's counterclaims.
The only real surprise here was the swiftness and thoroughness of Apple's victory. Judge Alsup basically ruled that the OS X End User License Agreement (EULA), which prohibits the installation of the software on non-Apple hardware, is legal and means exactly what it says.
If you want a Psystar Mac clone--there are six models starting at $600--you probably should order it soon. I don't think they are going to be around for much longer."
