Forgive any naivete of my question but I've been searching without a clear answer. I'm about to purchase a new Macbook Pro "13 2.26 and I'm planning to upgrade the drive to either a 500 GB (5400) or 320 GB (7200) as soon as I purchase it along with 4 gb of Crucial DDR 3 RAM. I realize I will have to reinstall Mac OS X immediately as I plan to transfer files from my near-dead old Macbook after performing this install. My question: is it that easy? Am I missing anything here? I assume as soon as I turn on the Macbook with the new drive and insert the install disc it will take me through all the installation steps and I can then transfer my old info through Disk Utility. But I've read reviews that state the drive needs to be partitioned for video memory and other needs that make this a more complex proposition. The basic question: what if any steps am I missing? Thank you for any and all help and suggestions.
