This is a great backpack overall and I'll continue to use it. My criticisms may actually be strengths for some buyers.

Pros:

1) Three main compartments - one for laptop, one "bulk" area and one smaller opening for pens, business cards and other miscellany.
2) Two water bottle holders - one on each side.
3) Small front compartment that works perfectly for holding my sun glasses
4) Small front pouch that I use to hold my ear bud headphones (too small to hold "real" head phones)
5) Padded straps and back are comfortable.

Cons:
1) It is too heavy. It's not very heavy, but it's got more weight than I would prefer when empty.
2) Too much back padding. I think this thing is built to last but I wish they had used less padding, which I think is adding to the weight.
3) Top luggage handle is somewhat convenient but ultimately isn't that useful and probably should have been omitted or made less bulky (it's rubberized).

I think this backpack will last me for years - it works perfectly for carrying a laptop, a tablet, an e-reader, books, food and water onto airplanes, which is what I use it for. I also carry chargers, biz cards, pens and a few travel items (inflatable neck rest, eye shades and notebook).

It handles this load without feeling over stuffed. Overall I'd buy this backpack again, though I do wish it was not as heavy.
