The only time you need a petroleum based liquid fueled stove is when it's really cold.
I recently bought a jetboil SOL, and tried it out for the first time a couple of weeks ago. I already love it for its speed and convenience for summer camping. Coffee in the morning is definately a survival item for me.
However, given the part of the country where I live, where it has been known to get "really cold" (now and then), I think I will also keep my white gas whisperlite in good working order!
