see title. I do need space, but it doesn't need to be huge. I'm not into huge hiking excersions but I'm into travel and journalism and intend to start taking my camera and laptop around with me more often, but I want space to fit a flash for smoothies and a lunchbox + various other things. I'm a vegan and it's nigh impossible to find vegan food in many places around the world .. and I'm not someone who can afford to eat out much.
I was also looking at the Targus TEB01, but I'm not really sure what to go for and if to go for one of the SLR specific bags, which seem a little over-specified and pricey (what if I'm not taking my camera out, are the lens sections useful still, etc?)
