I just noticed the crooked display, too. It's weird because when I first read this thread I didn't see any crookedness on my T1, but today it was just glaringly obvious. When a straight line was displayed at the bottom of the screen (via web browser), I could see that the screen was rotated about 2-3 pixels to the right.
Urghhhhhhhh... has anyone dealt with this issue with Sony US?
ps. I did a hard reset & format and that seems to have alleviated the problem. It still looks a few pixels off, but in Photoshop (with a digital camera picture) it doesn't look bad. Since it's hard to prove the problem, I guess I'll just have to live with it.
