Yes, I remember that thread, which I thought at the time dwelt far too much on the aesthetics and mechanics of sleeves, skins and shells, and far too little on cooling and whether any significant protection was actually provided.
Anyone whose Powerbook gets hot on the bottom should think about how much heat it's dumping that way before sealing that bottom panel inside a layer of plastic thick enough to prevent scratches to the aluminum. Plastic is a better insulator than conductor of heat, so more heat will be trapped inside the PB, and the fan(s) will have to run substantially more to keep it at a safe temperature. In a dusty environment, that means more dust sucked inside through the vents and clogging up the fan(s) and heat sink.
And using a Powerbook inside a shell isn't at all the same thing as using it on a tabletop, because its rubber feet create an airspace between the bottom panel and the table surface through which air can move (and moves much more readily if the back edge of the PB is propped up on something). In a shell, the only airflow across the bottom panel is outside the shell, with most of the heat retained inside it instead of being transferred to the air.
