Usually, there's always something about the first batch of released systems and handheld systems that is not working properly.
I remember that even GB Advance SP had a problem with screen, however this was not due to bad pixels, but dust actually being able to easily build-up inside of the protective glass. :-(
Sony had problems with every launch of a new system released so far. There was always something buggy or defective.
Solution...wait a while before purchasing for the bugs to get ironed out. ;-)
