Our main take-away from the 2013 CES was that this is going to be the year when OLED and 4K-rez “Ultra HD” TVs finally arrive. And by “arrive” I mean sitting in the store, waiting for you to buy ‘em. While this development is no doubt promising, you can also count on the advanced sets scheduled to hit stores later this year being expensive.

First it was shark attacks and the Gary Condit debacle, and then came September 11. The year 2001 wasn't a great one overall, but it was pretty good for high-definition television (HDTV), which continues to make steady advances despite the drooping economy.

Q My partner and I want to get set up for high-resolution audio and are hoping to use the Tidal service for better-than-CD-quality streaming. We have a Sherwood stereo integrated amplifier from the 1980s, along with big, beautiful, fantastic-sounding speakers and we don’t want to give those up. I’ve tried researching the huge range of available tech options but just don’t know how to make it work. We use Android devices and own a Fosi Audio DAC-Q4 [digital-to-analog converter/headphone amp]. We also have a spare computer that can be used to run Tidal. —Victoria Baker, via email
