The XXD class of cameras are very nice. There are plenty of good photographers on this an other pages that can make alot of great photos with those camera bodies.
For me the reason why the 1D class of cameras is leaps and bounds above the XXD class is it's dual computers.
I have never owned a 30D camera. I started with a 1D classic. Then bought a 20D, then sold the classic, then the 20D and bought (2) 1D MK II cameras.
There were two things that really made me not like the 20D. First problem was backfocusing and the fact that the AF points never seemed to catch on to what I wanted when I moved the focus point outside of the center spot.
The second was the fact that when I switched the focusing to the (*) button on the back of the camera, it would slow down FPS when I was shooting.
This is the reason why the 1D cameras don't have that problem is there is one computer specifically devoted to AF and the other is devoted to all the other functions of the camera.
When we went out and rented a MK II N it put us over the top where we knew we would never shoot with a XXD series camera. Now I don't know what changes they have made in the new 40D so I cannot say what it's like. But when making the move to the 1D series camera you will never go back to using the XXD class cameras as a main shooter.
