Leopard Delayed because of iPhone
April 14, 2007 — MazApple’s next operating system OS X Leopard, will be delayed due to the demand for the iPhone.

The operating system will now be released in October 2007, four months after it was originally expected.
It’s said that Apple want to hit it’s targets with the iPhone, so the the OS X engineers and quality testers have been assigned to the iPhone.

All I can say is oh bother, who wants an iPhone anyway?
