According to users on the PreCentral and EverythingPre forums, the Palm Pre may still have some hardware kinks to work out, with a number of users reporting some form of screen distortion. Having just launched, as you can imagine, those on Palm's design and distribution teams might soon be in the hot seat.
A majority of those who are experiencing the anomaly speak of a similar circular distortion which manifests at the bottom of the Pre's screen. More specifically, some describe it as a "yellow splotch" which resembles the effect of applying pressure to the screen with a finger. It also seems to be a general consensus that the discoloration gets worse as the temperature rises.
As we await for official acknowledgment from Palm, if you just laid down coin on the Pre, let's hear your impressions thus far, yellow distortions or otherwise.
