Steve Jobs announced at the WWDC keynote today that Apple is switching to Intel processors. MacNN has live coverage. The bottom line is that Mac OS X for the last five years has been running on Intel, the switch is expected to be complete in two years, and Rosetta will allow PPC apps to run on Intel-based Macs, transparently. So the rumours were still right then : for two years, the gossip runs that there was an internal version of OSX which was developped for Intel. Running Windows on a Mac should now be possible, but it won't be possible to run Mac OSX elsewhere than on Apple hardware.
