Elecom offers in Japan and many other places in the world, notebook sleeves named Zeroshock. As their name imply, these sleeves protect your computer against shocks. Now the VERY good product is available as a backpack!! So, Elecom offers in Japan the ZSB-BM007 (hey, Double-O-Seven is back!!), a Zeroshock backpack that can accommodate a 15.4” wide notebook. I finally found a backpack, and Totoro told me he was going to get one as well. The backpack will be soon available on GeekStuff4U.com!
