Hello everyone. A friend of mine has a sleeve (thin case) for her PowerBook 15", but she is unavailable and I would like to know who makes it, as it does not say on the sleeve. It is very thin, appears to be made of ballistic nylon, is silver on the front, black on the back, has a plastic window in the center of the front (for the Apple to show through), has an off-center black mesh netting on the back, and has what looks like an embroidered "S" on the back. Does anyone know what this is? TIA.
