Hi, After many months of deliberating, I have finally decided to dump my windows laptop and switch over to mac. However, I can't decide which macbook to buy. I will be a junior in college this year and am a Finance major so I am not going to use any of the heavy apps like photoshop. The laptop will mostly be used to write papers, surf the internet, screw around on iLife watch tons of movies and also play light games (if ever, AOE III and probably some other RPGs). I want something that won't be completely obsolete in like 3 years and I plan on upgrading things like RAM and HDD if I need to. I know I want the 15'' but then I am not sure. My limit is 2,000 (w/ student discount) and I am torn between the 2.53 w/ 250 GB and the 9400M and the 2.66 w/ 320 GB and the 9400M and 9600M GT. Is the upgrade from 2.53 to 2.66 really noticeable and will it make a huge difference down the road? Also, I am not a big gamer but will watch tons of movies and stream media so do I need the 9600M GT or will the 9400M work just fine? Also, I plan on upgrading to Snow Leopard when it comes out and both models would be compatible with it but is one going to be much better? Any help would be appreciated Thanks!
