Just recently picked up a Maxpedition Typhoon Gearslinger. It holds my 12" screen laptop, might hold a 13.3 but not anything larger. Has two outside pockets for accessory gear, a small pocket I put my ham HT in, a built in tactical flashlight holder and an interior pocket for either a 50oz hydration bladder or a weapon. Has single over the shoulder strap, waist strap and plenty of MOLLE webbing.

So far so good, seems well constructed and offers plenty of configuration options if you add some MOLLE pouches. I also use a couple of Grimlok carbiners to hold a water bottle and keys.
