Protection, just Incase
I carry my MacBook Pro in a backpack.
I like the backpack better than the traditional briefcase bags for several reasons, none that really need mentioning here. Anyways, the only problem with the backpack, is that sometimes things shuffle and tend to get pressed against my MacBook, opening the door to scratches and dings.
To prevent damage, I purchased the Incase 15″ Neoprene Sleeve from my local Apple store. Let me tell you, one of the best purchases of my life. The fit is snug and the padding is exceptional. I really don’t notice any additional weight, but I notice the added safety.
If you need added safety for your laptop, be sure and check out the selection at Incase.
