I would have liked Apple to offer a 9800 or something, and enable hybrid SLI. I understand the hit it would take on battery life, but perhaps it really comes down to an issue with heat. As cool as the MBP looks, it's svelte dimensions don't allow for much airflow. Shame, really. But I would still rather have a MBP than a flimsy plastic/partly plastic notebook. I'm looking at you, Fujitsu and Toshiba. Your durable metal cases are held together by extraordinarily flimsy plastic screen hinges. I've seen them break all too often. Don't get me started with Dell or HP, either.
That said, the price for Mac notebooks is hardly 3x the cost of competing notebooks. They bother to use higher quality components on their circuit boards. It really does make a difference, especially when using headphones and the electronic hissing noise of the mainboard circuitry is all but filtered out.
