This bag is great for a 3-4 day business trip (assuming you wear clean clothes every day and you dress like some suit monkey).
If you have the main compartment stuffed to capacity, it is tough to get into the outer 2big pockets, but those pockets are sized to hold things roughly the size of the bag face (I can fit a laptop into one pocket- but there ain't no padding, so be careful!) And I like that there's a soft-lined sunglasses pocket in the top, but it's hard to get into if the main compartment is stuffed to capacity.
It's a great bag, but it would be my dream bag if the outer pockets didn't get squished by the main compartment (i.e. if they sat on the outside of the bag, like a bump, instead of being constrained by the base plate footprint). So- it's a not a bad substitute for the MLC non-wheelie, but it's perfect if you'd rather frighten people in the concourse by racing up behind them making noises like you're about to run them over.
