Definitely more. I've read that sense of smell retains the most  
memory. When do we get smellovision?

Agreed. I waited until I could get a 1080p display for under $2k then  
jumped on it.

Funny. I never would have considered a 1080p display if I didn't have  
a great receiver and surround-sound to back it up.

Without guessing your age, I bet it's still a great sounding system.  
Oh.. and I don't consider having $10k to spend on ANYTHING  
"starving". :)

I've resigned myself to the fact that the masses are easy to accept  
severely impaired quality if it means fast and cheap. I just hate to  
see a project that has taken years in a studio reduced to a 1MB mp3  
on someone's cell phone. I do have an iPod and listen to it in the  
car since you can't really tell the difference between 256k MP3 and a  
CD over the ambient noise in the car, anyway.
