What to buy. The older 15 inch version looks btter specced (at least graphic card wise 9600gt comared to 320m) compared to the new updated 13 inch version. The dilemma now is because the price between the two has become so narrow as retailers sell off the older model the extra screen size and better GPU makes it so appealing. I know about the extra battery life and portability factor on the new 13 incher but apart from that is there any justification in getting this new model because your getting so much more with the older 15 incher. Baffling.............But I need to know. Thanks.
