I have a couple right near the top of the screen. But I didn't notice them until I was watching a movie or something where that section was all black. I've only actually seen them in that situation, so I don't worry about it because the rest of the time I forget they're there.
Yeah, within 14 days for UK and 30 days for US. I think everywhere else is 14 days. It's a good policy for their image, I'm sure they will replace a device for a dead pixel.
