Yes, but I don't like to think about it.

Comcast quite possibly will be watching you, but more likely for ratings gathering than for ensuring an audience of no more than x or at least y. I expect this box will be part of a voluntary program for monitoring household TV viewing habits. This would be similar to the existing Neilson electronic ratings system, only automatic, i.e. instead of requiring you to log into the system whenever you start watching TV and log out when you leave, it just detects how many are present.
I make my time back by slacking off at least 75% of my time at work.
A 40 hour week is far too much time to spend in a workplace; it does lead to slacking off, simply because most people can't maintain a high level of concentration for such long periods. And in reality we're talking about a minimum of a 45 hours a week, not 40, as most of us eat lunch at at our keyboards instead of leaving the office and taking the mandated break. This 40 hour work week minimum seems to be mostly an American tradition (misfortune?) too. Britain's typically have 35 or 37.5 hour weeks, often including lunch. I expect other European countries have similar or even shorter work weeks.
We should also not discount the effect long commutes have on our performance, either. I recently swapped a two hour daily round-trip commute for a 10 minute one and feel so much more capable each morning and much less dead at the end of the day.
I'm also unhappy about the insanity of the two weeks of vacation a year that most of us get starting new jobs, that just isn't enough to relax and recuperate, especially as it tends to be spread over a year and not taken as a single chunk. We should be aiming for a minimum of 4 weeks to start.
So to answer the original question - not a minute more and leave your work behind at the end of the day. Tell your employer that time spent outside of work with family and friends (and actually living life) will ultimately improve performance and productivity in work.
