I haven't had cable or satellite for 4 years, so this rings true for me. I go to bars or friends' houses to watch MNF, or I just skip more of them these days. Other than that, there's no way to get the current episodes of Dexter online without subscribing to Showtime.

Funny thing is...I'd pay for both MNF and Dexter a la cart on iTunes/Amazon if it we're available. As it stands, neither networks get any of my money. But the local bars do :)
