The PSP 3000, the next version of Sony's PSP, is getting poor reviews. Apparently the screen isn't up to much.

IGN said :

We received our review sample of the new PSP-3000 shortly after the reports of lackluster screen performance began to emerge. When we started up the PSP-3000, we immediately recognized the issue many users had begun to complain about. The problem is immediately recognizable when scrolling the home menu navigation. When moving quickly between the various media and settings icons, the scanning lines are extremely noticeable.

The most unfortunate effect of this is poor transitional effects in both media and gaming.
Looks like we won't be upgrading our PSP's anytime soon
