Definitely good news - my wife's computer is coming up on an upgrade next year, and I was decidedly unenthused about my choices in terms of cheap dual-core CPUs (the Pentium D, cheap CPU and wonderful overclocker that it is, isn't a great fit for an mATX box). Hopefully this will knock the 4400+ (which has a nice balance between clock speed and cache) down into the $150 range by Q2 2007.
Then again, if Intel executes well with Conroe, maybe I'll get her one of those. Isn't competition great?
