Even Freitag, those lovely truck tarp recycling chaps, bow down before the Cult of Mac with their Star Tek laptop sleeves. which are specifically designed for the Powerbook and iBook. They come in either fume stained white or yellow. As if having a Mac didn't push you into the 2% realm of the elite, this laptop sleeve will surely secure your place. Although it's not as skin tight as I had initially hoped, it still rocks pretty hard. The rubber exterior is waterproof as is the coated zipper, making it nearly impossible for water to weasel its way in there. There's also a nice cushy neoprene lining. And in all honesty, the slightly extra space is great for sliding in a pen and perhaps a thin book and papers.
