It's not so much that I insist the stove fit the pot, it's just one of those nice-to-have convenience factors. It would mean that when I'm ready to cook, I can just grab my kettle and a bag of food and head for the kitchen area. However, I keep the stove inside the kettle, set the canister on top of the lid (perfect fit in the groove around the edge), and drop both into a stuff sack - next best thing to everything in the kettle. (Bonus: in the case of the PR, it means I don't have to drag that useless triangular box around.)
