Hi, I wondered if anyone could give me an idea of what to expect when my base 13" MBP arrives soon. I currently have a late 2006 15" 2.16 C2D with 3GB RAM. Things have been going a bit dodgy for a while, battery, trackpad button, screen is not so good, so I needed something new, and more portable. My usual tasks include surfing, emailing, iTunes, iPhoto, watching avi's etc in VLC and rendering some of them for ipod use. What sort of day-to-day difference can I expect?
