I don't have an input on the potential security risks of pen cameras on airlines, but I do have an opinion on your description of economy travel on modern airlines.

It's spot on, and unbelievable to me that there are no other options available for air travel. With the amount of time business executives spend in the air I have to imagine there is an airline company out there modeling the business case for increased ticket prices with the justification of companies subsidizing to make up for lost productivity.
