Since I bought my MacBook pro (April 2010) I have been using the Speck See Thru Satin Snap On Case. I am decently happy with it, and after 1.5 years of use, I can see it has done a good job of protecting my MBP. However after keeping a case on the computer so long, I began to find myself craving to use it without the case in the bare aluminum. Lately I have been toying with the idea of removing the speck case for good and using this sleeve when transporting my macbook, but I have yet to make up my mind. So, do you use a case? If so what kind? I love the bare aluminum unibody, but I just can't leave the house with it unless it's in a case.
