The big news at WWDC, aside from the forthcoming release of Leopard (the latest revision of OS 10) is the completion of Apple’s switch to Intel hardware. With today’s launch of the Intel Xeon-powered Mac Pro and Xserve, the last pieces of the puzzle have been placed on the board. This brings an end to Apple’s PPC-based products, and begins a new era under the Intel banner. On the bright side, these new machines are sure to bring a better performance per-watt than previous models. It will also be interesting to see what position Apple takes on virtualization now that their server line has moved to x86/x86_64 hardware.
