Ah, this thread was still active. Anyway, got my replacement PW2 and happy to say it is a clear improvement - no pin-holes, a straight screen and more even lighting. The best improvement is the straight screen and the lack of any distinct specks on the screen. The lighting is more even, but of course this is relative - it isn't 100% even and I don't think it will ever be. But it looks like a good specimen in the PW2 scheme of things.
More first impressions through here:
