Its not about being snobbish. I currently own a 24" white iMac and was seriously thinking about upgrading so i went to the local Best Buy and compared both models side by side. To be honest both models are pretty much the same inside, with the 24" having a slightly faster CPU, but not by that much.
The screen is where there is a huge difference, and I am not referring to size alone. The quality of the image and the angle of viewing are so much better on the 24". Lets say you are viewing white screen on both straight on, the 24" screen is brighter and whiter than the 20" screen. Now turn to the side and view them both at a slight angle suddenly the 20" screen becomes slightly "yellow" and dimmer while the 24" screen is still bright with no color difference. The larger the angle the more of a difference you will notice, and believe me it is a very big difference.
I am not crapping on the 20" model, it is a very good machine, but Apple could have done a much, much better job in regards to the screen, especially with an all in one computer such as the iMac.
