There's a really cool Nova show on the topic of reversal. They've even been able to roughly model the chaotic nature of the reversal, which happens very quickly. They've even found lava that showed the magnetic field moving tens of degrees during the time it took to harden. But it also describes how there are localized reversals that fluctuate. Check out the cool graphics:

Is this premature announcement of intent just an attempt to demotivate commercial companies from investing in competitive development?
Wake me up when it gets beyond vaporware.

Most people don't realize you can start by buying a terrestrial hdtv receiver and piping it to your regular television set. Why bother with HD receiver if you don't have an HD screen? Because:
No ghosting
No snow
Much lower signal strength requirements for good reception (get more channels sufficiently)
More channels. Metro stations all, at a minimum, simulcast in digital. Some, such as PBS, broadcast different programming on their several digital sub channels.
You can add the HD monitor later when they get cheaper or plug your computer monitor in for special occasions (if you make sure connectors are compatible.)
Remember, this is over the airwaves, free, no cable fees, nada. Just like your regular TV set but high quality signal (Though I'll say nothing about quality of programming.)

The chance to read thousands of pages of undigested government reports? I can't wait! Maybe just as soon as I've finished reading all my phone books.
