While professionally chic may be the look some people are looking for, I personally enjoy the simplicity and durability of my Incase laptop sleeves - or, if I need another pocket for my iPhone, iPod, or mobile device, perhaps checking out Laptop Covers by German designers Katja Hettler & Jula Tullmann. It's plain as can be, but may be just the thing to calm your nerves from potential technology over-stimulation.
Laptop Covers features an outside pocket (4" x 5") for your iPhone, iPod, or mobile device and has 2 hidden snaps to close tightly. The sleeve itself is made of primarily wool felt and has a cotton trim in various colors.
Manufactured in Germany, you can grab the 13" edition (only available in gray) or the 15" edition (only available in orange for $78 and $82 respectively.
