Thanks, Lisa, for the links and the update. It's good to see that the decision has pretty much been made. We like to play our PS3 and sometimes watch blu-ray videos, so it looks like we are part of the 3/4 blu-ray population.
The $10-$15 difference I was talking about was between blu-ray and regular videos. When we got the HD TV and PS3 for Christmas, I wanted to get my family a blu-ray video. The Spiderman movie had just been released and was showing on all the new HD TVs. I found a Spidermand video for about $16. I was happy until I talked to a salesman about what clarity we were going to see, just like in the store. He told me that was because they were playing "blu-ray" Spiderman. I was shocked that the price was going to be $29. That was what I was talking about people not wanting to pay the difference all the time.
There will be many movies that we will buy that won't be blu-ray because we won't care about the sharpness as much as the price. Luckily we will still have the choice of regular or HD.
