In reply to kevin stephens:
I (sorta) do. I am by no means a professional photographer (some of pics are in my profile), but enjoy taking photos. As a result, I can't justify a full sized tripod.
The potential issue with conventional tripods is that they are either heavy or too light to feel stable in windy conditions. You can hang a bag or something else heavy (like this:

Other problem is that the ground is usually uneven. Hence, legs of tripod must be adjustable as much as possible. Some stupid designs (like this:
http://www.kreitzspace.org/IMG_0662.jpg ) which does not allow to adjust the angle of a separate leg.
My approach for half a dozen years was Manfrotto MP3-D01 (a decent review here: ). It takes virtually no space/weight and easily supports bigger cameras (used it with up to 1kg cameras). However, it is really short and will not work on grass. Still good for rocky terrain and general travelling though. The best thing about it is that you can just keep it on all the time and deploy it in a second or so.
I am currently using a Gorillapod which gives me quite few options on how to place the camera, it is rather sturdy and works great in different environments. I didn't notice it freezing up in winter (I usually attach it to a rucksack's strap), but it might happen. It is yet not too heavy, has a little bit better tripod head and could be used in quite few different ways. It has rubber feet, too, which help to keep it stable. Out of curiosity, I also managed to wrap the Gorillapod around the trekking pole which made a "selfie stick". It worked in field conditions, but I never found the need of doing it (it was purely for fun!) and holding a trekking pole with a camera attached to the far end is quite scary.
