Hey guys, this will be my first MBP and I'm looking forward on getting the hi-end 15 inc. I've noticed that the 7200 no longer is the standard for the hi-end model. I really hesitate between a 750g 5400 rpm and a 500g 7200rpm considering that there is no price difference!!! I will mainly use my computer for everyday stuff + some audio processing. What do u suggest aand why??? thx!
