Ordered mine from Dell and noticed 2 "stuck" pixels. One is a bit more noticeable than the other because it's white and the other is red. It's not too bad even on the brightest setting but I have to really look for it to see them.

I decided to ask Dell for an exchange because I'm really picky, especially since I paid a lot for this phone. Suprisingly I got a new N900 the very next day (talk about service!). Sadly, the new N900 was even worse. It had 5 stuck pixels (1 white and 4 red/green dots).

I'll probably keep the first N900 because it's not too big of a deal, but what are the odds of getting 2 N900s with more than 2 "stuck" pixels... I'm worried about Nokia's quality control... but then again I might just be unlucky. However, I've never owned a phone or lcd tv/monitor that had any visible dead/stuck pixels.
