Now that the updates are FINALLY released, I am going to place my order for a 15" powerbook very soon. I have one dilemma, however: Is it worth $100 more to upgrade the VRAM to 128mb 9700 over the 64mb 9700, and will doing so delay my order because it is bto? The laptop will be used for light gaming, dvd's, internet. Any opinions welcome, thanks!
