quite expensive though unless you can get one made locally. But still I wouldn't trust people not tripping over tripod legs. The only stand I trust is a C-stand but who wants to leg that around just for the laptop?
ya.. that's the problem... I guess it depends on what kind of setup you have, how many assistants and what's SOP for you. Personally have thought of getting a table like yours but stop at the fact it's another heavy thing to carry on location, and the trouble in moving it about per angle/shot outweights its usefulness. It might be nice for clients so they don't have to bend up and down but for us we're used to it.
