It was all done in good intentions to make Elbonians eat the tomeato instead of mud, but of course the result is a total collapse of the Elbonian society structure.

Electronics do not keep working forever just because it does not have any moving parts. Capacitors leak and degrade, batteries start to grow hair, etc. The old, trusty 486 simply isn't as stable and nice to work with anymore as it was 15 years ago.
The electronics have EARNED their right to go to the electronics heaven!

I Denmark we have something called "Grundloven" (translates to something like "the basic law"). NOTHING can surpass what's written in this law. I sure hope that's the case too with your constitution...
B&O products are sold to wealthy people, who care a lot about the looks and brand of the equipment, primarily for use in the living room. Most of the intended audience actually don't care about the sound quality, which is kind of sad. And people who care about sound quality don't buy B&O equipment, because manual equalization is at town in Siberia to B&O.

Can you see it coming? The ultimate Windows root exploit!! Hmm... I guess someone has to go tell them. Othervise they won't notice it until it's too late...
Seriously, how do you dare to enable this kind of access?!?
There's a huge market for this because since the UWB technique doesn't require carrier waves and lots of power it doesn't require all sorts of power amplification as traditional communication methods.
So why is that cool? It means that UWB can be used as an inter IC communication method, thus eliminating the need of parallel buses!
When the antennas are becoming better (higher gain), the UWB technique will expand to have a larger range, which will expand the market even further.
Originally the term "Ultra Wide Band" designated a special modulation technique but in February 2003 the FCC approved a standard to define UWB-communication as a communication with a minimal 10-dB bandwidth of 20% of the center frequency.
The original modulation scheme associated with UWB works almost as Pulse Position Modulation (PPM): Within a certain, fixed time slot a very short pulse with high energy is emitted. The position of the pulse is decided by a in advance determined code scheme. Depending of the code scheme and the pulse position, the time slot is interpreted as containing either a 0 or a 1.
The powerfull short pulses can be shown to have a very weak and very wide representation in the frequency domain. Without knowing the coding scheme in a link, a UWB signal is thus seen as noise.
Walls and other obstacles tend to obstruct certain specific frequencies only. Since UWB signals have Ultra Wide Bandwith, UWB communication can theroretically go through all kinds of natural obstacles very easily.
The hard part in UWB is making an antenna, that can actually emit signals with this very high bandwidth. Normal antennas are designed to emit in a narrow band. Thus, to make UWB work flawlessly, a lot of research must be made to make a good antenna.

Bandwidth: The width (measured in Hz) of the band ind the frequency spectrum used to transmit a signal.
Data rate: Bits/s. Is often increased if the used bandwidth is increased, but not nescessarily!
Baseband signal: A signal that isn't put onto a carrier wave. Can be modulated in a non-carrier-wave fashion with different spread-spectrum techniques (DSSS (Direct Sequence Spread Spectrum), FHSS (Frequency Hopping Spread Spectrum, UWB (Ultra Wide Band) etc.)
Passband signal: A signal that is limited to a specific band in the frequency domain. Most often a bandwidth-limited baseband signal put onto a carrier wave by using FSK (Frequency Shift Keying), ASK (Amplitude Shift Keying) or PSK (Phase Shift Keying). Radio is transmitted this way.
Narrowband signal: A signal that uses a less bandwidth than the bandwidth within +/- 20% of the carrier frequency.
Broadband signal: A signal that uses a more bandwidth than the bandwidth within +/- 20% of the carrier frequency.
To summarize: Broadband ISN'T the opposite of baseband, broadband is a very meaningfull term and broadband doesn't imply high data rate.
ADSL services can have relatively high data rate. This does not make it at broadband service. The slow ADSL data rates doesn't use a sufficient portion of the frequency spectrum to be designated broadband. The higher ones (app. > 512kpbs) do.

It looks fancier and thus the wives can accept them in a living room.

I've actually never heard that word before, but I would suppose it to be so, since bandwidth is a measure of a width of the used frequency spectrum.
:-)
Spectral density, however, is an entirely different term...
Let's just get a few definitions straight:
Bandwidth: The width (measured in Hz) of the band ind the frequency spectrum used to transmit a signal.
Data rate: Bits/s. Is often increased if the used bandwidth is increased, but not nescessarily!
Baseband signal: A signal that isn't put onto a carrier wave. Can be modulated in a non-carrier-wave fashion with different spread-spectrum techniques (DSSS (Direct Sequence Spread Spectrum), FHSS (Frequency Hopping Spread Spectrum, UWB (Ultra Wide Band) etc.)
