A few days ago I had the time and urge to clean up my MacBook, as it had some dust building up in between the installed Speck Clear Case and the MacBook’s outer shell.
Much to my horror, when I removed the clear case, I found out that my MacBook’s shiny white outer shell was riddled with small scratches! I guess the clear case protected the MacBook from getting dents or scratches whenever it got some bumps, but it did not prevent the scratches caused when it comes into contact with the MacBook itself.
I never placed the Speck case back to prevent any further damage, and instead shopped for a replacement. I found this case that has faux leather on the outside, and something like felt on the inside. It’s the ProFolio from Clik.

Now I feel that I don’t need the sleeve that came with my MacBook when I bought it. Another thing that is eliminated is the need for a wrist-rest protector, since the leather extends to the trackpad area.
I hope this won’t lead to scratches on the MacBook’s case, ever. Now what I need is a scratch remover similar to those used on iPods.
