Picked up the 80 gig with a superdrive from the Apple re-burb store. I had an iBook (its in my sig, now goes to the wife) but this thing feels much more solid then the iBook. The keyboard feels much better, more solid. This is my second Mac, and transferring all of my files from the old book was so easy, I almost cant believe it. I had planned on spending the evening messing around, getting everything set up, but I dont have to do anything! Anyway, could someone explain how the ram in the PB works. I thought I was getting 512mb but when I open up About this Mac it says that 256 is built in + 512 installed for a total of 768 mb. Are all of the PB's like this? Anyway totally stoked on the new machine so far, especially for the price!
