I use this w/ my Tumi expandable laptop bag. Holds my Tom Tom, power supply for I Phone & Dell laptop, bluetooth mouse, MiFi, Bose headphones and various other misc items all in one bag! Big pockets on each side, I usually have an extra laptop charger in one of the pockets since I like to keep one charger in the hotel room and one w/ me when on a client site. The other pocket keeps pens, keys, ID badges, etc.  I travel weekly and anything that can help organize me is A+!
