Yeah you'll probly be able to play ps1, 2 and 3 games on it or some ****. I think that's pretty cool actually. And yeah, that price will probably come down in a while. I actually haven't seen one personally but I know there is a high end tv place here in Dallas that sells them. I'm sure they have a display model sitting around so I might go just gawk at it.
Actually I think there's a 4k monitor out there for like 800 dollars but I can't find any info on it. It doesn't matter though because I'd have to upgrade a ton of **** on my PC for it to pump that kind of resolution at good frame rates.
