Hi all. Just ordered the 15" PB...doubled the video ram...can't wait to get it. I've been reading this board for a while and I know there are all sorts of threads about newbies...but I'm really interested in the very first thing that I should expect with my new machine...right out of the box, is there anything special I need to do to to fully capture the Mac experience? And although I will do a search for this, I figured I'd ask anyway...I'm looking for a cool backpack that will protect my PB and still look cool...and nothing TOO big and outrageous...kind of subtle, but very effective. Thanks!
