As expected, the new Macbook and Macbook Pro were launched at the Apple keynote yesterday. The Macbook has experienced the most important changes, now becoming a miniature Macbook Pro:

The new 13.3″ Macbook has an aluminium finish and a Nvidia GeForce 9400M GS graphics card with 256 MB DDR3 memory. At the moment there are no published benchmarks for this card, but it is likely close in performance to the 9300M GS (Macbook Air has got this card, too). The weight has been reduced from 2.3 to 2 kg, the screen is LED-retroiluminated and the platform has been upgraded to Intel Centrino 2. But it does not have FireWire port, now. The new Macbook is available from 1299 $.
Both the Macbook and Macbook Pro have lost the button of the trackpad: now the whole surface of the trackpad can be used as a button, programming different areas for different actions.
An interesting novelty in the Macbook Pro is the simultaneous presence of two graphics cards: the same GeForce 9400M GS as in the Macbook, and a 9600M GT. Switching between cards enables you to choose high performance or long battery life. You have to log out to switch cards. The new Macbook Pro is available from 1999 $.
