You don't have to be POTS to be called a "phone line". ISDN is also a phone line system. Also, the phone frequency range is more like 400-3400Hz (ever noticed the lack of bass from the phone?), making bandwidth more like 3000 Hz with 8 bit per sample encoding. And in fact, that comes close to actual data rates achievable with a "56k" modem. I really hope we get a 56k expert in this thread at some point. You and I are obviously not experts. :(

CRTs do produce radiation in the X-ray wavelengths, which is dangerous to life forms. However, with modern CRTs, the leaded glass blocks enough to keep levels of X-rays safe. See http://en.wikipedia.org/wiki/Cathode_ray_tube#Ionizing_radiation

The manufacturer's curb weight of the Bel Air was 3,615. The published curb weight of the Malibu was 3,436. A mere 179 lbs is probably not the weight differential you were expecting.
