Hi all, I am on the verge of finally switching from my PC laptop and getting a new 15" 1.33 powerbook but am trying to decide on some of the finer details. Specifically I am wondering whether it is worth upgrading to the faster hard drive or is this money better spent on extra ram? I am currently doing a PhD in biochemistry and will be doing the usual student stuff but with some 3-d molecular modelling thrown in there. I know there will be some improvements but will the faster hard drive give me a noticeable performance boost for everyday uses??
