eBags offers the Osprey Porter 46-Liter Travel Backpack in several colors (Black pictured) for $89.99 with free shipping. (Amazon charges the same for some colors.) That's $7 under our mention from a month ago and the lowest price we could find by $40. It features padded laptop and tablet sleeves, multiple compartments, compression straps, padded hipbelt and sternum strap, and top and side handles.

Update: The price at eBags has increased; however, it's still available at Amazon for $89.99 with free shipping.
