Well I know I'm not the first one to ask this question but I have a hard time to decide. I want to buy my first Mac, switching from my 5 years old computer, I been shopping for a Mac for a long time (2 years) but I'm pretty sure next week will be the week I will order my computer. I finally made my mind for the screen, I will get the anti-glare HD screen. But I don't know if I should buy the 15" i5 2.4 or the i7. I was thinking of buying the 2.4 and update the hard drive later on. What I want to know is what kind of battery life are we looking at with a 5400 hard drive vs a 7200 hard drive. What I will do with the computer is game (Diablo 3 / WoW / CS:S and other), the normal browsing and watch movies. I will also use the computer for video and music editing. Could you please give me your input on this. Thanks for all your help. I might not reply for a couple of days because I will not have access to a computer. I'm going on vacation and I will try to stop by the Mac Store and see if I can look at the anti-glare HD screen and check the forum at the same time.
