Now this is a Big step forward (Score 1)

I've been waiting for this release for years now. Since the original Developer Releases of Mac OS X we all knew that Darwin could perfectly run in a generic x86 box, so the outcome was trivial: Steve was planning to switch to Intel, almost half a decade ago. It was becoming annoying to have a machine priced twice as high as a usual PC but with half the performance. C'mon, even though this Intel Core Duo notebook is brand new, 4 ~ 5 times the performance of the old G5 is laughable at best. Let's throw away the nonsense discussion around the "MacBook" name, the RISC VS Post-RISC (CISC), the Mac OS X VS Windows VS Linux, Power VS Intel, this is being picky, don't matter. The bottomline is simple: the Power is out of the game, the Mac OS X can grow the installed base faster, linux doesn't need to support yet another hardware architecture, open source can grow faster on Mac machines now. Virtualization, hypervisor and alikes will help people bring Windows on top of Mac faster than before. There's room for a lot here, can't wait for the next releases.
