Well, surprize surprize the PSP has a defect! After the whole PS2 defect thing back when that came out, you'd think they'd learn not to rush a product to release.
Defect Video 1: If you move/tilt the PSP even slightly while playing it, it shoots the disc out. Boy is that a set back or what.

Defect Video 2: If a PSP detects a Nintedo DS near it, it shoots the disc out at it. XD Sony wants their users to not own a DS, so the PSP is programmed to attack and destroy! (ok, not actually a defect... but still funny)

And apperantly this isn't an isolated event, complaints of projectile discs are popping up everywhere. lol
