the deadline is about television stations broadcasting in both non-digital and digital formats. By the end of dec. 2006, (unless they change the date, which they have many times in the past) broadcast stations are REQUIRED to send out both an analog and digital station. By the year 2006 they will no longer be required to send out the analog signal, which means that if you have an analog box, you will no longer get the station if the STATION chooses to not send out the analog signal anymore. These stations include NBC, ABC, CBS, Fox, etc. This does not mean the government is forcing everyone to stop sending out analog signals, or forcing consumers to buy digital cable, or forcing cable companies to only put out digital signals, it means it is giving television stations the right to stop sending out analog signals. If the government feels, in the up coming years, that this doesn't seem fair to consumers they will set the date back farther as i said they've done that in the past.

as for the digital cable, I love mine. If you had the satellite you're most likely used to knowing what it is that you're watching, when you flip to a channel, or turn on the TV. I really like knowing what it is that's on at the time. I also like knowing what's coming on later, and even before digital cable/satellite I found tv guides to be completely annoying.
hope this information helps.
