Ladies and Gentlemen, Boys and Girls of all ages. In 2010 Apple designed laptops which look great and (most of which) have the new processors by Intel. Unfortunately, people are ruining them with terrible protectors that cover up the beauty of the Apple Designers. So, please, for the love of humanity, STOP! It's a computer which you purchased because it looks awesome, Why would you put a case over the top of it unless taking it from destination A to B? I mean, seriously, the computer looks amazing and is made from metal and glass. The metal is aluminium right through, and (as far as I believe) it is not covered in paint. From this, the metal itself cannot decolourise. Now, for that piece of glass which rests in the middle, that really is a first for me, because since when did glass decolourise? Seriously...its glass! Maybe your past Macbook didn't have glass as the trackpad. If you really want to ruin your device with cases and all the bulls**t, then go get a PC and put Snow Leopard on it. If you weren't getting a Mac for the exterior design, then why did you get one? It really isn't worth the extra $1000 from a Dell Laptop in my opinion.
So, if you want my 2c, then forget it, and enjoy your laptop as much as you can before the next one comes out.
Good luck!
