I'm on my fourth bloody unit now. First one bought on friday, half a dozen dead pixels, two of which were slap bang in the middle of the screen. Fine for games, shit for movies. Exchanged for a second saturday morning. That one went back today: bizzarely warped screen at the bottom. What looked like little waves in the screen itself. Third one today had bubbles in the plastic of the screen and didn't even make it out of the shop. My fourth (and final) unit has a perfect screen, but the pop out slot where the discs go is slightly bent, so it doesn't sit flush against the main body of the unit.
It's a lovely, lovely thing, but I'm shocked at the build quality of the four I've seen. I'm not the type to take things back usually, but if they're going to charge $250 for it, it should come out of the box perfect imo.
Still, Wipeout and Lumines *are* absolutely lovely. A very very impressive bit of kit, manufacturing problems aside. I can only assume that the warehouse that supplied my local shops had a shitload of duds. Or Sony couldn't be arsed to check them properly, or something.
