MobileWhack.com reports that there is a new feature concerning the graphics chipset/battery:
For graphics you have nVidia’s GeForce Go 7400 with a twist – there’s a SPEED/STAMINA switch which you can set to get the performance you desire. With the switch set to SPEED you experience full graphics power in your 3D games and other video-intensive applications. Set the switch to STAMINA and you squeeze the max out of your battery.

Note: We are going to start carrying information on the 13-inch WXGA/widescreen laptops that have Carbon Fiber (or some other weight-reducing means) as some of these are smaller than their XGA 12-inch counterparts in both depth and weight.
