Picked up a 40D as a second body this week.
Used it for the 1st time yesterday.
Here's what I love about it.
1. The LCD. Man this thing rocks, it's larger, brighter and clearer and the magnification seems bigger than my 30D.
2. The AF is seems so much faster.
3. 6.5 fps. If you have a heavy hand watch out. Took a few minutes to adjust from my 30D
4. The on body grip so much better than the 30D.
You can see some shots here and here.
Oh btw here's what happened to my 30D
