Well, the S90 is no 5D Mark II, but it served its purpose last night on my trip to the airport: burdened with baggage and with only one hand free, I never could have taken this if I only had the big camera. Even if I had it packed, I never would have been able to get it out of the bag and take the shot with only one hand. With the S90, I just reached into my jacket pocket.
