Well I went to frys with my wife today and decided to take a look at cameras. I swore that I wouldnt look thru the viewfinder of a 40D a while back...
Well I told her it cost a little more than my L lens I just purchased, then she said then dont look at the price of this camera over here...
Well at that time I had put the 40D upto my eye and snapped a few shots, played with the controls (how do you turn the LCD on? I couldnt change AF points either on that camera!) I even tried burst, but it was set to low and half the buttons on the display didnt work.
Then I looked at the camera she pointed out, which was a 5D and I put it upto my eye. OMFGWTFBBQ! Thats about the best way that I can describe it. It was like going from 640x480 to 1920x1200 for the first time. Funny thing was that when I looked at my shot on the LCD there was only half the image, since the shutter had failed
Even the XSi had a bigger viewfinder than my XTi 
To my ear the 40D shutter sounded soft. I guess Im too used to the sharp 'can hear from a mile away" shutter on my XTi. I think that the 5D sounded perfect.
I fought the urge and am now holding out the the 40D successor...
