From my point of view if you bought a $3000 laptop, it's worth (if you can afford it) to buy a $200 case to protect it. An example, about a year ago, my friend and I both had 17" PB's. I bought the Brenthaven bag and he bought a bag from office depot for $50. We were traveling together and on the trip, both of our bags took similiar dives

. Mine was protected and didn't get hurt. His case got dented on the corner where the superdrive was and the gray plastic liner was then bent and in a U shape blocking his superdrive's slot. That isn't a perfect example, but it's all I got. Good luck.
