Like any technology, DTV is no panacea. Some issues to consider:

• Cost: HDTV prices will remain high until more people find a reason to buy them. DTV tuner cards are around $100 but they currently require a 400 mHZ computer. Standalone DTV set-top boxes ($150) may still be too high for the people who need it most.

• Content Availability: Some producers may avoid DTV until there's a solid market, though PBS plans to push the content envelope

• One-way distribution: DTV is unidirectional; broadcasters may
  transmit content through DTV spectrum, but the general public can't.
  What media will serve as backchannels? The Net?
