And to think, I'm in a 'greenie', super enviro-nut (yes, I drive a Prius, and I've had only compact flourescent bulbs since 1999; and am seriously looking at switching from THOSE over to LED bulbs, which are still $30 a piece...,) yet I'm in the process of replacing my G4 server with a massive beast... I must say, though, the thing makes an excellent space heater.

I don't think Prius is that good either. By the time you pay $5000 over a Corolla (or is it more or less now, I don't know), are you really saving money on gas for the lifetime of the car? I don't think you are. Especially when you have to buy new batteries after 5 years because yours are spent up and don't work well anymore.

However, CFLs are smart. They last 5x longer and use 4x less energy even if they cost twice as much initially. Just by the fact that they cost 2x more but last 5x longer, that's 2.5x the value over old bulbs on that one metric alone.
