Looking for a very large laptop backpack

As a result of my previous thread, I've come to the conclusion that I just need a gigantic laptop bag to fit my gear.

My gear includes:
Alienware m15x 15.4" laptop
Google Cr-48 12.1" laptop
Power adapters for both laptops
1800 page 3-4" thick programming book
Several screw drivers, tools, and multitools
A CD case (One of those large 60+ CD 2-per-page holders)
A laptop cooler
1-2 mice
Mousepad
Headphones
External hard drive (laptop drive so its not too big)
Miscellaneous other small gear

So my question is, what are some of the largest laptop backpacks available? My 2 major requirements are: 1) a dedicated pocket to hold/protect one laptop, and 2) very very durable to carry the weight of all the above items.

I appreciate the help! I've put several hours into reading reviews here, searching amazon, searching Google, viewing various bag manufacturers websites, and I'm not finding exactly what I need.. or maybe I am and I just can't tell. Some of these bags look so large in the pictures and then they only fit smaller laptops.

 

Think I posted these in your other thread:
M.A.S.K. Laptop Backpack
Photo Backpacks by booq

If possible, get something with a shoulder or a waist strap, it will make carrying everything easier (think I also recommended this in the other thread).

 

Yea I really like the MASK backpack.. I've looked at it several times since you posted it in my previous thread and I'm close to purchasing it.

The booq packs are also nice, but I think the most appropriate sized booq pack is $200 and thats a bit more than I'd like to spend on a backpack.

Still open to other suggestions, but I'm really looking at the MASK now.

 

just a few more suggestions:
Orion
Spire Volt
Targus Revolution

 

Just ordered a Slappa M.A.S.K.

Thanks for the advice, guys!

EDIT: Kinda disappointed. I tried to use a coupon I found online - 50kWinner10716 - and it worked great. 10% off. Well, I originally was going to pay with my Paypal account, but then I decided to pay with my debit card as I get points/rewards for doing that. When I canceled and went back to place the order again the coupon had expired (its a one time use coupon so they probably had already marked me as having used my one use). I emailed Slappa support... hopefully they still give me the extra 10% off!

 

They probably will.
The people at Slappa are awesome.

 

Woot! Just got a message from Dominick on my support case.. He applied the coupon code. Awesome service!
