It seems that there is a potential problem with Sony's new (in America) PSP - dead pixels in the display. Contrary to rumors floating around the Sony message boards Sony will replace defective units, but you have to send it to Sony Computer Entertainment - America (SCEA) and they'll send you a replacement. So you'd be without it for a week or so. Pretty annoying - but it doesn't change the fact that I want one.
In other PSP related news, here's an article that will show what the PSP looks like opened up. Needless to say, try this at your own risk - you'll void your warranty if you open your PSP. Then where will you be if you start having trouble with dead pixels?
