You know, I thought the same thing.

I'd like to have both. And, with our interest in multi-use items, maybe we can come up with something.

I'm thinking a metal water bottle (Alum, steel or Ti), that doubles as a cook pot with a removable top. Maybe there's something out there already?

Maybe something like a nalgene bottle that un-screws at the top shoulder. Remove the o-ring and cook away...

Heck, it could even be a metal pot with a plastic lid with a canteen top built in.
