but that same article that you link to has this as it's conclusion:
"It's certainly exciting that, if luck and money came to my side, that I can go out and buy a laptop and know I won't be deprived from the PC gaming world. Unfortunately the chances of us landing a review unit to show you guys just how nifty the new GeForce FX Go series are is about as high as me getting asked into marriage with Penelope Cruz. Not many companies are willing to hand out $3,000+ laptops, after all. So we'll have to settle with this information we get to share with you. And if you ever get a laptop with the GeForce FX Go chip in it, be sure to brag to us and make us wish we had $3,000 to spend on a nice gaming laptop. 😉"
regarding ibooks, I think Apple will have to be very careful not to step on the 12" PB's toes with this update, while still offering an upgrade worth noticing. I'm interested to see how they'll manage this balancing act...
