For months now, I have had my 13 inch Macbook Pro in a Speck hard plastic case. I took it off today, only to find around 3 nicks on the bottom of the laptop. My question to all of you, is whether or not you think a hard plastic case on Apple products is even relatively necessary, because it seems like most of the "accessories" I have been buying do more harm than good. Also, the Aluminum shell looks depressing under all that protective plastic so I don't think I will be putting the case back on. What do you all think? Naked Macbook, or protected Macbook?
