Thats probably a subjective experience. I fly twice a week and am always in a hurry, always running a little under the clock and it aggrivated the &&^%$# out of me to have to start unzipping bags and pulling things out when i need to be focused on removing my shoes, coat, and pockets and just getting through the darn line.
As far as the utility of the bag, i dont really have that issue with the overnighter version as it has a second compartment in it large enough to hold 3 shirts, 3 ties, socks, underware or a large referene book and a few dozen files along with scarf, gloves, and over sized chargers like the power brick.
Now for a bag just to use for once in a while tsa check points, i would not chose this bag. For someone who flys twice a week like i do....i will never have a traditional bag again.
