I searched and this seems to be the best forum for this question. I have a Kata HB-207 backpack (Amazon.com: Kata HB-207 GDC Hiker Backpack for DSLR system or DV/HDV camcorder. (Insertrolly optional): Camera & Photo) which has been great up until now, as I have a new laptop (Asus G74SX) that is too big for it. The laptop has a 17" screen, so I need a new backpack that has lots of slots or compartments or configurable dividers for camera gear (I have a Canon XH A1 and a T2i plus lens and accoutrement) and a compartment for the laptop.

Any suggestions?

I have the Kata BP-502 Camcorder Backpack KT BP-502 B&H Photo Video which has been superseded by the Amazon.com: Kata KT PL-PV-610 Pro-V-610 PL HDV Backpack - Black: Camera & Photo

Be aware both exceed airline size limitations. The BP 410 may be better for you is size matters.
