Co-worker confused about Blu-ray

[Grisle]

I was talking with a co-worker today trying to get him to purchase a Ps3 when he asked "why would I do that?" To which my first reply was "for the Blu-ray movies!" He said if he was going to do that he might as well get high definition movies...I said these are high definition movies...and he said no I mean get a real High Def player. I was getting mad at this point...I said what do you mean by real...and I told him why I thought Blu-ray was the better choice.
Then he says that he thought Blu-ray was just for the Ps3 like UMD was for the PSP...has anyone else come across this? Is the Ps3 synonymous with Blu-ray to the average consumer? Do they not know the awesomeness? I hope that people don't think just because the letters DVD are in HD-DVD that it's the only real high def format. Anyways, I had to tell somebody...do you guys think there is another BOGO next week?
