If your precious PowerBook G4 means the world to you, then brace yourself: This fabulous design just got repackaged with some Intel firepower. The MacBook Pro (15-inch) is the new standard for Mobile Mac users. Gone are the slow IBM PowerPC processors, and in come the Intel Core Duo processors, raising the Mac performance bar like never before. For consumers, this is a huge deal. But graphics and media professionals should wait until their essential software apps are updated to universal binary (to be optimized for Intel-based systems).
