Basically, yes. I had a thread about the HD in a MBP, I was told you had to buy the HD from apple to have them put it in for you, but I am unsure. I figured I would take mine into CompUSA and get them to replace it with a new HD. But anyway, if you can get the 3 GB, get it. I'd upgrade the HD as a built to order option when you buy it, unless it's something special (like that 250 GB drive I'll be putting in the new MBP I'm buying soon).
