Well, that may be, but here are a couple of points:
1. The Steady may indeed hold your camera, as it held my big Kodak pretty well. It may not be an ideal tripod for it, but there was no hint of my Kodak slipping or flopping to one side or the other.
2. It is what it is- no one complains that Suzuki Swifts aren't that good off road because they aren't designed to go off road.
3. I would think that in many cases as a serious photographer you would want your knife or tool while the camera is set up already so you can "set up" the shot.
That's not trying to crap on your suggestions, I'm just thinking that while it might not fit your needs perfectly, it may still work out well enough for you. Or it could simply be that you are trying to get too much out of it. I'm certain if the Steady is successful enough then Gerber may come out with the Steady HD for larger cameras- you never know....
