Right now I have a white macbook. I carry it back and forth with me all the time to school. Either in a shoulder bag or my bookbag. So it bounces sometimes, depending on how many books I have with me. The sleeve I have for it seems kind of thin and I believe it may be why my hard drive crashed. This was it: http://www.builtny.com/showPage.php?pageID=1563 What would you recommend that would absorb the shock from the slight bouncing in my bookbag? I do not want a hard case like spec either. I was thinking this one: http://www.applesac.com/peonylace.html Will that one be good for what I need? Anything else you guys recommend? Also I may be purchasing a new 13in macbook pro in September. Something I could use with both would be good.
