While I'm not a fan of DRM or buying non-physical media, I am a big fan of free, and Amazon is offering on their Unbox the NBC premieres for free before they are broadcast on television.NBC, if you recall, was recently ended negotiations with Apple about pricing for their shows (A leaked story at Variety seems to indicate that Apple was considering dropping TV shows to just 99 cents. While Apple won't be offering the complete season (unless things are renegotiated), it seems as if Amazon will be offering the complete season pass for download.
Amazon Unbox uses 1-click after your first download, so make sure you click on the one that says "Buy episodes with 1-click", and NOT "Subscribe to season with 1-click".
My own favorite of the shows being offered is Chuck, about an IT guy drawn into a world of epsionage. Just don't take it too seriously and you'll have a good time.
The science fiction time travelling show "Journeyman", apparently features someone using an upside iPhone.
