abi-
shieldzone is a good choice (but it does not cover the screen-only the outside case and palm rest).
or if you want style, you can go with

or if you are hesitant on putting stickers on your macbook, you can go with various protective sleeves that are discussed at
http://forums.macnn.com/showthread.php?t=295885
i'm not sure if the last link works...if not, ask about sleeves on this forum and people won't be hesitant on giving their favorites ๐
personally (i don't have the macbook yet but will very soon!), i am first gonna get a sleeve for my macbook (since i will be carrying it around in my backpack) and i might invest in the shieldzone (that only covers the bottom part since i will using my laptop conservatively-whatever that means ๐
hope this helps!
