New MacBook Pro

The new MacBook Pro (15 inch screen) comes with both integrated graphics and a graphics card for extra graphics performance. I hope this is a really good feature. For ordinary work you can use the integrated NVIDIA GeForce 9400M graphics processor so as not to punish your battery too much. Then when you do some heavy duty graphics work you would otherwise do on a desktop machine, you can switch to the NVIDIA GeForce 9600M GT with up to 512MB of graphics RAM. That sounds really smart.
However they have not released the 17 inch version of the MacBook Pro yet. I am itching to know whether they will bump up the processing power further. In any case it would be great to have this feature. I own an older one and it was certainly an inspired purchase. For graphics work you need that bigger screen.
In the UK you can get the 15 inch MacBook Pro here:
Personally, I’b buy straight from Apple because I love the ease with which I can configure the purchase, but other vendors may offer better deals with RAM, AppleCare etc. If anyone does get one (I am holding off for the 17 inch version, depending on cash-flow!) please let me know how the graphics switching feature pans out in real life.
