Excellent post.
Above is the best thing about gravity systems. Let it run while you're doing other things - if you are going to filter a lot of water at once.
I used to use pump filters back in the day. A buddy of mine I used to backpack with used them and we would share the filter for our group outings. When I got my own filter set up I went with a gravity system - the Katadyn 10L system. There are many variations of gravity systems - the Sawyer line being some. No matter what route you go they beat the heck out of pumps. Gravity filtering has transformed my camping experience, no matter what the activity. I don't feel I have any limitations with water with a gravity system - as long as I can access a water source.
