Greets Rzenznikj,
Do you have any information as to where it states that it's illegal to install it on a generic X86 pc? Is that because they only sell an "upgrade" version?
I'd like to see them try to enforce that in court in any case.
Apple is afraid of competition and makes it illegal to install on a standard PC, do a search for OSX86 on google or yahoo
It's against the EULA for OS X, and IIRC, Apple served OSX86 with a DMCA infringement notice.
Though if they did offer a copy for standard PC's, I'd snap it up in a heartbeat and just run that. Heck, I'd even pay $150 for a copy...8^)
