Hey all. I have a few questions. I will be out of town for awhile but I will have my trusty powerbook with me so I figured I would ask some questions to keep me entertained on the road. I know this was addressed in a post earlier but I will ask here as part of my list of questions. 1. What is a good sleeve that does not cost too much? 2. Is there a good way to cool the powerbook while it is in my lap? What products will do this and what are their names? 3. What product will clear the keyboard, palm rest and mouse button as they get dirty over time? 4. Should I be worried about denting the aluminum case under normal use? You responses would be much appreciated Thanks!
