I'm thinking of buying the 13" MBP 2.53GHz C2D and I thought of the idea of buying it as is with the warranty and buying a WD 500GB 5400RPM HDD separately. I did the math for configuring a MBP with the 500GB HDD option and one without it and adding the WD from Newegg on the side (Tax included). The difference came out to about $65. Is it worth paying a little more to have the 500GB HDD already installed and configured or do it myself. I already have a Snow Leopard copy my dad bought and I know how to mechanically install it. But my beef is that I heard you have to partition it a certain way or it won't work. I dunno if it's true or not. If anyone has a thought on this or personal experience on this subject, it would be greatly appreciated. BTW: Yes I am aware that the MBP is WAY overdue for an update (thinking it'll be announced at the WWDC). I just want an opinion on the whether or not I should get the HDD separately or with the computer.
