Cleaning the unibody
I would use a clean microfiber towel or cloth rather than a paper towel as the paper towel could scratch the surface.
I purchased a self adhesive skin (available from Amazon-forgot the brand) that has a carbon like look and texture to it. It has an opening where the lighted apple is on the top lid. When I went into the Apple Store for a setup appointment, got lots of looks and inquiries about it, has a nice cool factor.
The kit came with the edge pieces, but I think the set was sent to me was for the 2010 model and some hole cutouts were either missing or backwards, so the edges of my Macbook "Pear" (2011 '13 w/a 128 SSD) are the brushed aluminum. What is nice is at least on the top and bottom lids, there are small holes for the screws and the proper indents for the the lid where the hinge and opening are.
I transport it in a Tom Bihn Cache which is a custom fit.
Happy Macbook Pear owner.😉
