That's a nonsensical question. Some sensible people will say no, but some sensible people will say yes. If your free time revolves around television and you make too much money, what's wrong with dropping an extra $300?

And the market says "yes".

In a third-floor walk-up it is.

If it saves $5 a month in electricity, that extra $300 pays for itself in 5 years, meaning all the other benefits (widescreen, being able to carry a 42" alone, less space consumed) come free.
