Keith's note: Scott Parazynski and I did a number of live video chats with Miles O'Brien while while we were at Everest Base Camp exactly 3 years ago. Miles was originally supposed to have joined us but ended up being stuck in his laundry room in New York which doubled as his media studio. Toward the end of this video I pulled out a piece of hardware and teased the audience to guess what it was and its purpose. I don't think I ever asked for reader comments at the time. So ... anyone care to guess what I am holding and why we had it with us?
