This for those of us with long memories smacks of the reverse engineering of the bios by compaq in the early days of pc's to produce the first "ibm compatable"... now if compaq did not win the legal disputes, to this day we would all be using IBM branded boxes or apple ones, depending on ones leanings. the Chameleon, rebel, PC-EFI, EFI-X etc are NOT line for line copies of apples EFI and proprietry code, rather like the early compaq bios clone of IBMs its a reverse engineered solution, it spoofs mac osX into thinking its running on mac hardware, same as the compaq bios fooled dos into thinking it was running on an IBM PC, like those early IBM's the new macs use off the shelf hardware, intel cpu's, ram, hard drives etc, and the only thing diffrent to a PC is the proprietry code in the EFI and the slick interface of os X running on top of a open source BSD base, and a fancy case, i hope like IBM in the 80s, Apple are forced to open up the OS to run on non apple hardware, let them charge more, say $150 instead of $29 (or £s if your in the UK like me), they whinge it would be less stable, so what let the end user take the risk if they choose to do so, or publish an official Hardware Compatability List, updated regularly to reflect changes in processor, memory, mainboards etc, and only support it on that mixes of hardware, it would still be cheaper than a "proper" mac. in short, i can see this gettin messy, like IBM its a bit late the horse has bolted, as soon as Apple moved from power PC to x86 it was a matter of time before os X was running on stock PC commodity hardware. wise up apple, let the OS run free, charge more for it, publish HCL lists, make your money from support, selling ipods and iphones, and let those that are willing to pay over the odds for outdated hardware pay it for a shiny box. but on the other hand increase market share, sell the os to anybody that wants it, who knows it may just be the best thing they ever did.
