With the introduction of multiple products it is easy to be overwhelmed, here a just a few notes of interest regarding the new products which weren’t mentioned in yesterdays event.

MacBook and MacBook Pro

Apple has published a support document which details how users can switch between using the integrated GPU in the MacBook Pro or the dedicated.

The change which requires the user to log out and back in again should offer better battery life when the user opts to use the integrated NVIDIA GPU (9400M). Currently it is unknown whether removing or plugging in the MagSafe automatically makes this switch.

Macworld is reporting that the new MacBook and MacBook Pros support the iPhone headset, the microphone works as an input and the clicker works as expected as well.

If you click the button on your iPhone headphones, iTunes pauses. Click again, and the music resumes. A double-click advances one track, and a triple-click moves back a track—just like on the iPhone.

Also unclear is the memory limit on the new notebooks, officially Apple lists 4GB as the memory ceiling. But the new NVIDIA chipset support DDR3 memory which is being used in the notebooks which technically supports 4GB sticks, creating a theoretical ceiling of 8GB.

24-inch Cinema Display

Apple lists the speaker system on the display to be 2.1, suggesting the presence of a subwoofer.

Apple offers adapters to use the new notebooks on other displays but not the other way around. Only the current MacBook, MacBook Pro and MacBook Air notebooks can drive the 24-inch Cinema Display.

Despite DisplayPorts ability to pipe audio and video Apple requires the USB to be plugged in to enable the speakers.
