I have come to love Ogio bags after getting one on sale and one for my wife. I have the Flux bag and just wanted more padding in the main compartment and space to put my computer stuff and books. The flux has great shoulder straps with that strap across your neck so you carry it and don't really notice it there unlike most bags with two plain straps you can feel the bag hanging and tugging on your back...Pros:Bag has firm back padding and nice neck and shoulder straps. It feels like the Flux improved. When you fill it up and tighten the straps you don't feel this bag on your bag, great for traveling or students.I love the quality and color of the bag, nice pockets for your stuff and nice padding materials in all areas of the bag.Fits my 15.4 inch Dell Laptop with the num pad on the keyboard, says fits a 17 inch haven't tried but this is a longer 15 inch laptop so it might...Cons:If I have to give one, compared to the Flux the more compartments take a little space away from the pocket for your cables and the main compartment but you get much better protection and padding for what the bag is carrying so it's a win loose not a complaint...
