I recently found out that there is a 1.5TB drive and am considering upgrading my iMac to it. However, I have a questions before I do this. I'm going to do a fresh install of Leopard on the new drive. I pretty much have most of my data backed-up but one question is iTunes Apps for the iPhone/Touch. How will I go about backing my Apps up? Do I just copy the Apps folder to an external drive and drag it back into the same location after? How will iTunes pick it up? An explanation of how this will work is greatly appreciated. Thanks!
