Yes, but you have no windscreen on a small gas stove like that. In a stiff breeze (or more), I'd take the Caldera Cone set up every time. The pot in a Caldera Cone is a whole lot more stable than a pot on top of a small gas stove.

As for crushing, it could happen, but when I pack up my Caldera Cone and slip it in the Ziploc container, and then nest the container inside my titanium pot, things are pretty well protected. Foolproof? No. Reasonably secure? Yes, I think so.

I don't find the Caldera Cone all that limiting with it's pot-specific design. The trick is to pick a pot (and matching cone) that works for what you do. I've got an MSR Titan 0.85L kettle. It can be used as a mug, pot, or kettle. It has a full-width opening, so there's no difficulty with cleaning or getting things out of the pot/kettle as there is in some designs. True, you can't do real cooking, but the Titan kettle is still fairly versatile. When I'm out on the trail, I keep my food prep fairly simple for the most part anyway, so the Titan kettle works for me. I wouldn't try to fry a trout in it though.
