I see in your sig that your rig is an M18x. Paying alienware for their largest backpack will cost you $120. Just get any backpack and something like this for protection:
I have a microsoft 15.6" backpack and it feels kinda heavy when my laptop is in it with other books. Might get a different one or something from alienware like, the orion bag I heard it has anti-phone hacking pads or something like that! xD
It has this safety-scan feature for airports, but it doesn't really work all that well because airport staff doing give a s#@% and search your bag manually anyway...
No, it turns out I was right! Alienware includes a pocket, that is anti-signal proof so your phone doesn't have ANY wifi or service! Its perfect if you are a criminal and you think cops can track you by phone! xD Must be some space material!
those cut offs on phone signal are great for people travelling, avoid international roaming charges, keep phones silent during meetings or class, keep people from using nearby systems to tap into your phone and get your info. There are many uses, but in all honesty is more of a novelty.
Personally, I bought a swiss backup a while ago. A little over two years ago to carry my HP 12.3 inch laptop in. Will be good for my alienware m17x as well.
This backup is DURABLE. Ill say it again. D-U-R-A-B-L-E!!!. I am very rough on things, and this back has been through kinds hell and back with me, and has held up far past my expectations. If you are looking for a good backpack to use, then this is definitely the one.
there are a couple listings on amazon, and sold in stores like best buy. Shop around, but definitely recommended.
