I do want an i7 decent battery life is all i want 2 hours or so of pure use should be fine. I know you can get more but i would have to sacrifice the speed that i want in my computer. Everytime i use my laptop anyway I have my AC adaptor so a 2 hour life or so is fine but i do want it to be portable the alienware isnt exactly that it weighs like 10 pounds and is 2 inches thick
