Its much better than my old white one, that aged faster than the knock knock jokes! I used to clean the white one once every month to get dirt off it from my palms and even then it came up glossy rather than the original matte. it got small scratches all over it and in general looks used and abused, even though it wasn't. the unibody on the other hand looks just as good as the day i got it, no changes in the finish, not getting dirty. I guess they are the advantages of aluminium. I am careful not to drag it across hard surfaces so that i don't get a grain of sand or whatever make a scratch in it but it certainly doesn't scratch in normal handling.
