I am going away to University soon and am unable to take my desktop with me. The reasons I wanted to buy the macbook pros were mainly because of the Battery life and longevity I heard they have. The laptop will mainly be used for word processing, web browsing/IM and a slight bit of gaming. The gaming is really the issue here as I can't decide whether to go for the entry level 13" (upgraded to 500gb HDD) or the entry level 15". The gaming will probably be kept to a minimum and won't be too intensive, I'm talking Counterstike, Starcraft 2 rather than Crysis. I'm not sure between the two, is the £500 price hike really worth it for the 330m? Will it really increase the performance of starcraft 2? And is the price hike worth it for the HD stuff?
