One of my criticisms about the new unibody Macbook is the component looks great after I clean it with iKlear, but soon after the areas surrounding the trackpad smudges and look dirty. I see this in the Apple store: http://store.apple.com/us/product/TV058LL/A?fnode=MTY1NDA2OA&mco=MTA4OTI1MjA&s=priceLH but it seems to be for older Macbooks. I'm wondering if anyone has any solutions aside from constantly cleaning this thing. The slippery surface isn't all that comfortable, so I'm not opposed to something similar to the aforementioned product. Thanks!
