This may be old news to some, but...
I'm using Nikon's Camera Control Pro and the issue of "Where to put the Laptop" has arisen. This is what I'm using and I reeeeeally like it!
Very solid and adjustable - it even tilts. Originally designed for court reporters. Mine is the portable, lightweight version, but they have heavier versions, too. I'm thinking about getting another one to hold a small monitor facing the model/subject. For safety, I always use the supplied Nikon 6' USB cable tied to the camera tripod base, then connected to the USB extension cable w/booster, then another 6' USB cable tied to the laptop tripod base. That way, if I (or some one else) snag the extension cable, it just unplugs at either end instead of toppling over ($$$). I am looking for a flat extension cord cover to use with the USB extension cable - since I use three Nikon SB-800s and one SU-800 on my D70, I'm wireless except for the extension cable.
Wireless in West Florida,
PS I always use a small sandbag to weight down the base of each tripod or lightstand just to provide a little more protection.
