AnandTech: "Today Apple announced updates to its MacBook, MacBook Air and MacBook Pro lines. The notebooks aren't available until tomorrow, but I've started putting together some analysis on the specs. It turns out there's quite a bit of give and take in Apple's new announcements; you get more, but you do give some up.
The new notebooks are also very important as they put to rest rumors of NVIDIA's departure from the chipset business, at least at this point. All of the notebooks I'm talking about here use a brand new Intel chipset by NVIDIA, called the GeForce 9400M. Apple is actually the first OEM to announce support for the 9400M, the chipset itself doesn't actually launch until tomorrow."
