I don't need 1:1, but I'd love some large format 4:3 sizes. I have a 30" 16:10 Apple Cinema display as my main monitor and a rotated 4:3 20" HP LCD on my right. While I like the 30" monitor, I'll admit the sides of the screen go to waste. But I love the height, and I like being able to compartmentalize onto the second monitor. In my mind, a great setup would be two 4:3 equivalents of the 30" display side by side. So instead of 2560 x 1600, it would be 2133x1600. Same height, less width. And I like having two because of the organization issue.
