I am super anal about scratches and etc. I upgrade my products on nearly an annual basis or every other update. I like to be able to represent my computer in like new condition. I also take pride in everything I own and keep it in immaculate condition. I have a new 15" BTO unit on the way but I'm almost afraid to use it until I can get at least a palm rest cover and a sleeve or something to put it in my bag. I have a sleeve from my 17" MBP that I guess I could use since the dimensions are bigger than the current 15" but that just looks sloppy.
