Hi, everyone. Long time lurker, first time poster. I'm going to be purchasing a MacBook Pro soon. I've been saving for 6 months and going back and forth over which model to buy. I've finally settled on the 15-inch 2.2 GHz since I still need to buy Adobe CS3. My dilemma arises after reading of the possibility of an updated and/or new MBP in January. SO... do I buy NOW or WAIT another agonizing month-and-a-half only to see that the updates aren't as impressive as I'd hoped and that it's more expensive than I wanted. I would greatly appreciate some input.
