As pathetic as it is, I think of my computer as an extension of me, in that I want to keep it safe from bumps and bruises like any good mom. I take the time to select a comfortably padded bag or sleeve for my laptop, so shouldn't I want to protect it at home? Acme makes soft, sleek, and extremely attractive iCovers, not only for laptop screens, but Apple cinema displays and monitors. I actually hunted for something like this a year or so ago for my monitors and couldn't find it, so I sewed it. Maybe someday I'll be brave enough to post my instructions, but all I can say is that they don't look near as pretty as the iCovers.
Prices range from about $30 to $80, and they even take custom orders.
