Who would have believed it7 After what seems like an eternity of tantalizing hype about "high-definition" television, the first digital sets are actually on their way to the market. This much anticipated debut would seem to be terrific news for tube lovers. As promised, the sets deliver super-sharp digital pictures, wide-format movie-style screens and magnificent stereo surround sound.
So should everybody rush out to buy one Well... maybe not. HDTV’s obvious advantages over conventional sets are offset by significant disadvantages. For openers, there’s the price tag. Sony’s small set, with a 34-in screen, lists for a fairly large $ 8,999. Prices will eventually drop, of course, but Bill Mannion, general manager of Panasonic’s TV division, acknowledges, "It’s going to be a while, maybe years before most consumers can afford HDTV."
Even if you’re a gadget freak with deep pockets, you may t
A. be likely to accept HDTV.
B. still think about lines of resolution of the programs.
C. buy HDTV, but with hesitation.
D. easily understand what HDTV is.
