I have a white 13-inch Macbook and was looking to get a sleeve for it. The Incase Neoprene Sleeve 13-inch MacBook caught my eye. But on the Apple site, there were some issues with it, the main being that it leaves black marks on the white Macbook. A quote from one of the reviews: "I've had a red Incase for about 4 months now and it has been great till this last weekend when I discovered red stains on the sides and bottom end of my white Macbook. It happened within one hour of placing the Mac in the sleeve and removing later to discover these stains." Written by GP 22 January 2008 Anybody have this sleeve and any issues with it? Also feel free to give me suggestions for other sleeves if you like. Thanks in advance, guys!
