I was just wondering if a keyboard guard protector is a good thing to buy for my new MBP. If so are there any certain ones i should look at. http://www.mygearstore.com/Products...ok-Pro-Aluminum-Unibody-and-Macbook-Air-Black That had caught my attention because i love switch easy products. When it comes to this type of accessory do they all do the same job? Thanks.
