The four wires are for upto 2 phone lines. This has nothing to do with DSL/Phone. DSL and Phone traffic are carried on the same pair, just on different frequencies. In fact, new houses have phone lines with 3 or even four pairs of wires. For upto four phone lines.
I am not even talking about local programming in HD. These stations don't even pass through the HD network programs. They actually downconvert. Seems backward to me!!
That is not true. Most TV stations in smaller cities cannot afford to go HD. So they are only doing SD. For example, I lived in Erie, PA until recently and only the PBS there is 1080i. Everybody else is 480p 4x3. CBS is not even digital. They have not even started their transition!
OTA = Over-the-air as in broadcast over the air waves using Radio Frequency (RF). These broadcasts can be either UHF/VHF/FM and either analog or digital. While UHF/VHF/FM relate to the carrier wave of the radio frequency, analog or digital refer to the decoded date.
Analog TV standardized on a modulated analog signal with the following characteristics
NTSC: 720 x 480 interlaced (every other lines are updated at each scan). Scan freq is 60Hz.
Digital TV standardized on a digital stream of data (still carried on a RF wave over-the-air) with the following varied characteristics:
ATSC:
720 x 480 interlaced
720 x 480 progressive scan
1280 x 720 progressive scan
1920 x 1080 interlaced
Advantages of switching to digital:
1) Government makes money by auctioning analog frequencies that the stations got for free long time ago
2) Broadcasters have the ability to multi cast (multiple streams of video/audio inside one channel).
3) Broadcasters have the ability to send high definition signals
4) Support for dolby digital and other surround formats
While there are inherent advantages in keeping up with technology and entertainment standards, the only thing that is going to force people to change their current behavior is the phasing out of analog OTA broadcasts. This will force people that watch these to buy a $50-$75 converter box that will convert the digital OTA broadcast into a analog signal that their current TV can display.
Personally, I own two HDTVs (one with built-in tuner and one without). I have not watched analog in a while. I am a big proponent of digital TV.
There are times when you have to force certain issues on people. It is just like Apple removing serial ports and printer/modem ports from the iMac in 1998 and going exclusively with USB. This started the proliferation of USB devices and now everybody is enjoying the advantages.
It is also like certain cities and states abolishing smoking in indoor public places such as restaurants. While certain people complained initially, it is great to go to a bar and not be drenched in smoke and stink. Sometimes, a good forceful direction is what the society needs.

Actually Mac OS X allows both hex and ascii, they separate that clearly. You can choose which kind of password you are about to enter and then enter the appropriate phrase.
In the Star Trek universe, Phoenix is the name of the first warp capable ship built by Zephram Cochran 10 years after World War III. Hopefully the Borg don't do time travel to destroy it in 2007.
Resistance is futile! Oh well - I miss Star Trek Next Generation. The new ones suck!

Considering Steve Jobs is a Vegan, I doubt that would have been of any use :)
