This decision will require both network and cable broadcasters to continue providing an analog feed to their customers even though all of them have spent literally multi-millions of dollars gearing up and getting ready for the new digital age of television viewing.
I have analog coming into my home right now, mostly because it's cheaper than digital plus the cable company wanted to charge me a lot of money for "home-runs" to the TV's. At the time I had no digital TV's either.
Today, I don't really have digital TV yet (it's been an expense thing) -- I have a lot of component video and I do IP streaming from the video server near my router to the living room.
Until you get a larger and more recent TV in place, it's hard to justify the extra expense, both to install and recurring.
Once the incoming signal is digital, you will need these digital-to-analog converters for each analog TV you have. At the store, if you have to buy them, it's going to cost you about $20-30. Not counting whatever equipment your cable company wants to charge you (probably built into a set-top-box)
Note that some of the problems with DRM have been reported, and also all of that DRM code in Windows Vista has had various folks up in arms.
